Accumulator

In a computer CPU, an accumulator is a register in which intermediary arithmetic and logic results are stored. Without a register like an accumulator, it would be necessary to write the result of each calculation (addition, multiplication, shift, etc.) to main memory, possibly only to be read right back again for use in the next operation. Access to main memory is slower than access to a register like the accumulator because the technology used for the huge main memory is slower (but cheaper) than that used for a register.

The canonical example for accumulator use is adding a list of numbers. The accumulator is initially set to zero, then each number in spin is added to the value in the accumulator. Only when all numbers have been added is the result seized in the accumulator written to main memory or to another, non-accumulator, CPU register.

Superscalar

A superscalar CPU architecture implements a form of parallelism called Instruction-level parallelism within a solitary processor. It thereby allows faster CPU throughput than would otherwise be possible at the same clock rate. A superscalar architecture executes more than one instruction during a single pipeline stage by pre-fetching several instructions and at the same time dispatching them to redundant functional units on the processor.

History

Seymour Cray's CDC 6600 from 1965 is often mentioned as the first superscalar plan. The Intel i960CA and the AMD 29000-series 29050 microprocessors were the first commercial single-chip superscalar microprocessors. RISC CPUs like these brought the superscalar idea to micro computers because the RISC design results in a simple core, allowing straightforward instruction send off and the inclusion of multiple functional units on a single CPU in the inhibited design rules of the time. This was the reason that RISC designs were faster than CISC designs through the 1980s and into the 1990s.

Swan

Swans are large water birds of the family Anatidae, which also includes geese and ducks. Swans are grouped with the intimately related geese in the subfamily Anserinae where they form the tribe Cygnini. Sometimes, they are considered a distinct subfamily, Cygninae.

Swans typically mate for life, though "divorce" does sometimes occur, mainly following nesting failure. The number of eggs in each clutch is between 3–8.
The word is derived from Old English swan, akin to German Schwan, in turn derived from Indo-European root *swen (to sound, to sing), whence Latin derives sonus (sound). Young swans are known as cygnets, from the Latin word for swan, cygnus. An adult male is a cob, from Middle English cobbe; an adult female is a pen .

Lopping

Lopping, also known as tree lopping and topping, is the practice of cutting trunks and branches of a tree in an effort to contain the tree's size or shape. Lopping is differentiated from other styles of pruning by where the cuts are made. When a tree is lopped, the cuts are made internodally, or not at branch unions and collars at the correct angles, leaving a piece of protruding timber that is called a stub.
Lopping in many cases is careful an inappropriate pruning method for amenity trees. The lopped stubs may regrow adventitious epicormic shoots which are bonded only to the bark. These epicormic shoots can grow dynamically and, unless regularly pruned off, may outgrow the original height and spread of the tree. Further, the ends of the lopped stubs are exposed to pathogens which may enter and infect the tree.
In orchards, fruit trees are often lopped to encourage regrowth and to keep a smaller tree for ease of picking fruit. The pruning regime in orchards is more intended and the productivity of each tree is an important factor. In an orchard, though, the natural longevity of a tree is often compromised in favor of its output in fruiting. Orchard trees are also carefully monitored and treated with fungicides and insecticides to minimise losses.

Genetics

Genetics is the science of heredity and variation in living organisms.Knowledge that desired characteristics were present at birth has been implicitly used since prehistoric times for improving crop plants and animals through selective breeding. However, the modern science of genetics, which seeks to understand the mechanisms of inheritance, only began with the work of Gregor Mendel in the mid-1800s.
Mendel observed that inheritance is basically a discrete process with specific traits that are inherited in an independant manner. These basic units of inheritance is now known as "genes". In the cells of organisms, genes exist actually in the structure of the molecule DNA and the information genes contain is used to create and control the components of cells. Although genetics plays a large role in determining the appearance and behavior of organisms, it is the interaction of genetics with the environment an organism experiences that determines the ultimate outcome. For example, while genes play a role in determining a person's height, the nutrition and health that person experiences in childhood also have a large effect.

Water abstraction

Water abstraction, or water extraction, is the process of taking water from any source, either temporarily or permanently. Most water is used for irrigation or treatment to produce drinking water.Depending on the environmental legislation in the relevant country, controls may be located on abstraction to limit the amount of water that can be removed. Over abstraction can lead to rivers drying up or the level of groundwater aquifers reducing unacceptably.The science of hydrogeology is used to assess safe abstraction levels.

Peripheral Component Interconnect

The Peripheral Component Interconnect or PCI Standard specifies a computer bus for attaching peripheral devices to a computer motherboard. These devices can take any one of the following forms:

An integrated circuit fitted onto the motherboard itself, called a planar device in the PCI specification. The PCI bus is common in modern PCs, where it has displaced ISA and VESA Local Bus as the standard expansion bus, but it also appears in many other computer types. The bus will eventually be succeeded by PCI Express, which is standard in most new computers, and other technologies.

The PCI specification covers the physical size of the bus (including wire spacing), electrical characteristics, bus timing, and protocols. The specification can be purchased from the PCI Special Interest Group (PCISIG).

History of Lipstick

Lipstick is known to have been used around 5000 years ago in very old Mesopotamia, when semi-precious jewels were compressed and applied to the lips and occasionally around the eyes. Women in the ancient Indus Valley Civilization applied lipstick to their lips for face beautification. Its original purpose was for Egyptian prostitutes to make their lips look like a vagina. Ancient Egyptians extracted purplish-red dye from fucus-algin, 0.01% iodine, and some bromine mannite, which resulted in serious illness. Cleopatra had her lipstick made from compressed carmine beetles, which gave a deep red pigment, and ants for a base. Lipsticks with sparkling effects were initially made using a substance found in fish scales called pearlescence. Lipstick started to gain popularity in the 16th century, during the reign of Queen Elizabeth I, who made blood-red lips and stark white faces a fashion statement. By that time, lipstick was made from a blend of beeswax and red stains from plants.

The Extended Industry Standard Architecture

The Extended Industry Standard Architecture is a bus standard for IBM compatible computers. It was announced in late 1988 by PC clone vendors as a counter to IBM's use of its proprietary Micro Channel Architecture in its PS/2 series. EISA extends the ISA bus architecture to 32 bits and allows more than one CPU to share the bus. The bus mastering support is also enhanced to provide access to 4 GB of memory. Unlike MCA, EISA can accept older XT and ISA boards — the lines and slots for EISA are a superset of ISA.

Although somewhat inferior to MCA, EISA was much favored by manufacturers due to the proprietary nature of MCA, and even IBM produced some machines supporting it. It was somewhat expensive to implement, so it never became particularly popular in desktop PCs. However, it was reasonably successful in the server market, as it was better suited to bandwidth-intensive tasks. Most EISA cards produced were either SCSI or network cards. EISA was also available on some non-IBM compatible machines such as the Alpha Server, HP 9000-D, SGI.

MIPS(Microprocessor without Interlocked Pipeline Stages)

MIPS designs are used in a lot of embedded systems such as the Series2 TiVo, Windows CE devices, Cisco routers, and video game consoles similar to the Nintendo 64 and Sony PlayStation, PlayStation 2, and PlayStation Portable handheld system. Until late 2006 they were also used in a lot of SGI's computer products.

Near the beginning MIPS architectures were 32-bit implementations, while later versions were 64-bit implementations. Multiple revisions of the MIPS instruction set exist, including MIPS I, MIPS II, MIPS III, MIPS IV, MIPS V, MIPS32, and MIPS64. The current revisions are MIPS32 (for 32-bit implementations) and MIPS64 for (64-bit implementations). MIPS32 and MIPS64 define a control register set as well as the instruction set. Several "add-on" extensions are also available, including MIPS-3D which is a simple set of floating-point SIMD orders dedicated to common 3D tasks, MDMX which is a more extensive integer SIMD instruction set using the 64-bit floating-point registers, MIPS16e which adds density to the instruction stream to make programs take up less room, and the recent addition of MIPS MT, new multithreading additions to the system similar to Hyper Threading in the Intel's Pentium 4 processors.

Key

A key is a device which is used to open a lock. It typically consists of a specially-shaped piece of flat metal, with cut notches , and/or milled grooves which fit the shape of the lock and can open the properly combinated lock by (usually) being turned in the lock housing. This portion of the key is referred to as the blade. The wider grip, referred to as the bow, is establish at the top of the key to facilitate turning. regularly, there are only a small number of keys which can work a certain lock. In some residential locks, all of the keys for a lock are given to the purchaser of the lock. Duplicates of the key can usually be made by anyone with the correct key blank and key machine. Some manufacturers assign an identification number to each lock and key combination. Knowing the identification number of such a lock allows a duplicate key to be made at certain places. Many residential keys are recognized by the key cuts stamped on the key bow.Most people in modern society use keys on a daily basis, to secure their home, their vehicle, or to access their workplace, among other uses. Those that use a number of keys will typically place them on a ring or key chain, often with other items such as key fobs.

Education System

Schooling occurs when group or a society or an individual sets up a curriculum to educate people, usually the young. Schooling can become systematic. Sometimes education systems can be used to promote doctrine or ethics as well as knowledge, and this can lead to abuse of the system.

Life-long or adult education have become extensive in many countries. However, education is still seen by many as something aimed at children, and adult education is often branded as adult learning or ultimate learning.

Adult education takes on several forms, from formal class-based learning to self-directed learning. Lending libraries provide cheap informal access to books and other self-instructional materials. Many adults have also taken advantage of the rise in computer ownership and internet access to further their casual education.

Aerial Archaeology

Aerial archaeology is the study of archaeological leftovers by examining them from elevation. It is one of the oldest prospecting methods. It is very productive and cheap, Aerial archaeology is frequent opinion that an aerial archaeologist is sitting in an aero plane, trying to discover archaeological sites and to take a few good photographs of them. To perform aerial archaeology you can also used satellite images, thermal images or airborne radar images. The advantages of gaining a good aerial vision of the ground had been long appreciated by archaeologists as a high viewpoint permits an enhanced appreciation of excellent details and their relationships within the wider site context. Early investigators attempted to gain bird’s eye views of sites by hot air balloons, scaffolds or cameras attached to kites. Following the invention of the aero plane and Aerial photography helps military during the First and Second World Wars, archaeologists were able to more effectively use the technique to find out and record archaeological sites.

Major ice ages

There have been at least four main ice ages in the Earth's past.

The most basic hypothesized ice age is believed to have occurred around 2.7 to 2.3 billion years ago during the early Proterozoic Age.

Main article: Snowball Earth.
The most basic well-documented ice age, and probably the most severe of the last 1 billion years, occurred from 800 to 600 million years ago and it has been recommended that it produced a Snowball Earth in which permanent sea ice extended to or very near the equator. It has been recommended that the end of this ice age was responsible for the subsequent Cambrian Explosion, though this theory is current and contentious.
A negligible ice age occurred from 460 to 430 million years ago, through the Late Ordovician Period.

Sediment records viewing the changeable sequences of glacials and interglacials during the last several million years. The present ice age began 40 million years ago with the growth of an ice sheet in Antarctica, but intensified during the Pleistocene with the spread of ice sheets in the Northern Hemisphere. Since then, the world has seen cycles of glaciations with ice sheets advancing and retreating on 40,000 and 100,000 year time scales. The last glacial period finished about 10,000 years ago.

The timing of ice ages throughout geologic history is in part restricted by the position of the continental plates on the surface of the Earth. Small changes in solar energy can tip the balance between summers in which the winter snow mass totally melts and summers in which the winter snow persists until the following winter. Due to the positions of Greenland, Antarctica, and the northern portions of Europe, Asia, and North America in Polar Regions, the Earth today is considered prone to ice age glaciations.

Proof for ice ages comes in various forms, including rock scouring and scratching, glacial moraines, drumlins, valley cutting, and the statement of till or tallies and glacial erratic. Successive glaciations tend to distort and erase the geological evidence, making it difficult to interpret. It took some time for the current theory to be worked out. Analyses of ice cores and ocean sediment cores unambiguously show the record of glacial and interglacial over the past few million years.

Transistor

The transistor is a solid state semiconductor device which can be used for amplification, switching, voltage stabilization, signal modulation and many other functions. It acts as a variable valve which, based on its input current (BJT) or input voltage (FET), allows a precise amount of current to flow through it from the circuit's voltage supply.In essence, a transistor have three terminals. A current or voltage applied through/across two terminals controls a larger current through the other terminal and the common terminal. In analog circuits, transistors are used in amplifiers. Analog circuits comprise audio amplifiers, stabilised power supplies and radio frequency amplifiers. In digital circuits, transistors function basically as electrical switches. Digital circuits include logic gates, RAM (random access memory) and microprocessors.Transistor was also the common name in the sixties for a transistor radio, a portable radio that used transistors (rather than vacuum tubes) as its active electronic components. This is still one of the dictionary definitions of transistor.

Postage Stamp

A postage stamp is proof of pre-paying a fee for postal services. Usually a small paper rectangle which is attached to an cover, signifying that the person sending the letter or package has paid for delivery, it is the most popular option to using a prepaid-postage envelope.

History

In it he argued that it would be well again for the sender to pay the cost of delivery, rather than the receiver who could refuse the letter if they could not or did not want to pay, as occasionally happened at the time. He also argued for a uniform rate of one penny per letter, no matter where its destination. Accounting costs for the government would thus be cut; postage would no longer be charged according to how far a letter had traveled, which required each letter to have an individual entry in the Royal Mail's accounts. Chalmers' ideas were finally adopted by Parliament in August, 1839 and the General Post Office launched the Penny Post service the next year in 1840 with two prepaid-postage symbolic envelopes or wrappers: one valued at a penny and one valued at two pence.

Three months later on the first prepaid-postage stamp, known as the Penny Black was issued with the profile of Queen Victoria printed on it. Because the United Kingdom issued the first stamps, the Universal Postal Union grants it an exemption from its rule that the recognition of the issuing country must appear on a stamp in Roman script for use in international mails. Before joining the U.P.U. many countries did not do this; there are very few violations of the rule since this time, though one example is the U.S. Pilgrim Tercentenary series, on which the country designation was inadvertently excluded. Because of this the numerous early issues of China and Japan often confound new collectors unfamiliar with Oriental scripts. A stamp must also show a face value in the issuing country's currency. Some countries have issued stamps with a letter of the alphabet or designation such as "First class" for a face value. Because of the U.P.U. rules their use is restricted to domestic mail, but breach of this rule is often tolerated. Exceptions to this are the British "E" stamp and the South African "International Letter Rate" stamp.

Asian Paradise Flycatcher

The Asian Paradise Flycatcher, also known as the Common Paradise Flycatcher, is a medium-sized passerine bird. It was in the past classified with the Old World flycatcher family Muscicapidae, but the paradise flycatchers, monarch flycatchers and Australasian fantails are now usually grouped with the drongos in the family Dicruridae, which has the majority of its members in Australasia and tropical southern Asia.

The Asian glory Flycatcher breeds from Turkestan to Manchuria. It is wandering, wintering in tropical Asia. There are resident populations further south, for example in southern India and Sri Lanka, so both visiting migrants and the in the vicinity reproduction subspecies take place in these areas in winter.

This species is typically originated in thick forests and other well-wooded habitats. Three or four eggs are laid in a cup shell in a tree.

The adult male Asian Paradise Flycatcher is about 20 cm long, but the long tail streamers double this. It has a black crested head, stale joke upperparts and pale grey underparts.

By their second year, the males of the wandering Indian race T. p. paradisi begin to obtain white feathers. By the third year, the male plumage is totally white, other than the black head. Males of the sedentary Sri Lankan race T. p. ceylonensis are forever stale joke.

The female of all races resembles the stale joke male, but has a grey throat, minor peak and lacks the tail streamers.

Jet Airways

Jet Airways is an airline based in India, helping familial and worldwide routes. The airline operates over 250 flights to 44 destinations athwart the country, with the majority of flights operated from Chhatrapati Shivaji International Airport, Mumbai. It presently controls about 40% of India's aviation market.

Background

Jet Airways was recognized on 5 May 1993 with a fleet of 4 Boeing 737-300 aircraft, with 24 daily flights helping 12 destinations.

Operations

Its 44 destinations contain most of the big cities in India. Its international destinations contain Kathmandu, Colombo, Singapore, Kuala Lumpur and London's Heathrow Airport. Jet Airways was the first personal airline of India to fly to international destinations. It was later joined by Air Sahara. The daily Delhi-London service started in October of that year.

Jet Airways and Air Sahara are the only personal airlines which survived the Indian business downward spiral of the 1990s. On January 19, 2006 Jet Airways announced that it is buying Air Sahara for $500 million. This is the biggest takeover in India's aviation history and the resulting airline will be the countries biggest.
In 2006 Jet Airways will be raising its way network from Delhi via the north Indian city of Amritsar, as it is to begin Amritsar-London and/or Amritsar-Birmingham.

History of sport

There are artifacts and structures that propose that the Chinese engaged in sporting activities as early as 4000 BC.Gymnastics appears to have been a well-liked sport in China's ancient past. Monuments to the Pharaohs indicate that a number of sports, with swimming and fishing, were well-developed and regulated several thousands of years ago in ancient Egypt.Other Egyptian sports incorporated javelin throwing, high jump, and wrestling. Ancient Persian sports such as the conventional Iranian martial art of Zourkhaneh had a close connection to the warfare skills.Among other sports that originate in Persia are polo and jousting.

Telegraphy

Telegraphy (from the Greek words tele = far and graphein = write) is the long-distance transmission of written messages without physical transport of letters, initially over wire. Radiotelegraphy or wireless telegraphy transmits messages using radio. This definition includes recent forms of data transmission such as fax, email, and computer networks in general. (A telegraph is a machine for transmitting and receiving messages over long distances, i.e. for telegraphy. The word telegraph alone generally refers to an electrical telegraph.) Wireless telegraphy is also well-known as CW, for continuous wave (a carrier modulated by on-off keying, as opposed to the earlier radio technique using a spark gap).
Telegraphy messages sent by telegraph operators using Morse code were known as telegrams or cablegrams, frequently shortened to a cable or a wire message. Later, telegrams sent by the Telex network, a switched network of teleprinters similar to the telephone network, were identified as telex messages. Before long distance telephone services were willingly available or affordable, telegram services were very popular. Telegrams were frequently used to confirm business dealings and, unlike e-mail, telegrams were usually used to create binding legal documents for business dealings.
Before fax machines came into general use, wire picture or wire photo was a newspaper picture that was sent from a remote location by a facsimile telegraph. This is why many fax machines have a photo option even today.
Optical telegraphs and smoke signals
The first telegraphs were optical telegraphs, with the use of smoke signals and beacons. These have existed since ancient times. A semaphore network invented by Claude Chappe operated in France from 1792 through 1846. It helped Napoleon enough that it was widely imitated in Europe and the U.S. The last commercial semaphore link left operation in 1880.
Semaphores were able to communicate information more precisely than smoke signals and beacons and consumed no fuel. Messages could be sent at much greater speed than post riders and could serve entire regions. However, like beacons and smoke signals, they were dependent on good weather to work. They required operators and towers every 30 km (20 mi), and only send about two words per minute. This was useful to governments, but too expensive for most commercial uses other than commodity price information. Electric telegraphs were to reduce the cost of sending a message thirty-fold compared to semaphore.

Camera

A camera is a device used to take pictures (usually photographs), also singly or in sequence, with or without sound, such as with video cameras. The name is derived from camera obscura, Latin for "dark chamber", an early mechanism for projecting images in which an entire room functioned much as the internal workings of a modern photographic camera, except there was no way at this time to record the image short of physically tracing it. Cameras may work with the visual spectrum or other portions of the electromagnetic spectrum.

Fog

Fog is a cloud in contact with the ground. Fog differs from other clouds only in that fog touches the surface of the Earth. The similar cloud that is not fog on lower ground may be fog where it contacts higher ground such as hilltops or mountain ridges. Fog is different from mist only in its density. Fog is defined as cloud which reduces visibility to less than 1 km, whereas mist is that which reduces visibility to less than 2 km.
The foggiest place in the world is the Grand Banks off the island of Newfoundland, Canada. Fog is common here as the Grand Banks is the meeting place of the cold Labrador Current from the north and the much warmer Gulf Stream from the south. The foggiest land areas in the world are Point Reyes, California and Argentia, Newfoundland, both with over 200 foggy days a year.

Photographyv

Photography is the method of making pictures by means of capturing light on a light-sensitive medium, such as a sensor or film. Light patterns reflected or emitted from objects are recorded onto a sensitive medium or storage chip through a timed exposure. The process is done through mechanical, chemical or digital devices well-known as cameras.
The word comes from the Greek words phos ("light"), and graphis ("stylus", "paintbrush") or graphê, together meaning "drawing with light" or "representation by means of lines" or "drawing." usually the product of photography has been called a photograph. The term photo is an abbreviation; many people also call them pictures. In digital photography, the term image has begun to replace photograph.

Science and technology in Japan

Japan is a foremost nation in the fields of scientific research, technology, machinery and medical research with the world's third biggest budget for research and development at US$130 billion, and over 677,000 researchers.
Some of Japan's more important technological contributions are found in the fields of electronics, machinery, industrial robotics, optics, chemicals, semiconductors and metals. Japan leads the world in robotics, possessing more than half (402,200 of 742,500) of the world's industrial robots used for manufacturing.It also produced QRIO, ASIMO, and Aibo. Japan is also home to six of the world's 15 biggest automobile manufacturers and seven of the world 20 largest semiconductor sales leaders.
Japan has also made headway into aerospace research and space exploration. The Japan Aerospace Exploration Agency (JAXA) conducts space and planetary research, aviation research, and growth of rockets and satellites. It also built the Japanese Experiment Module, which is slated to be launched and added to the International Space Station during Space Shuttle assembly flights in 2007 and 2008.

Minerals and rocks

A mineral is a obviously occurring, inorganic solid with a definite chemical composition and a crystalline structure. A rock is an collective of one or more minerals. (A rock may also include organic remains and mineraloids.) Some rocks are mostly composed of just one mineral. For example, limestone is a sedimentary rock composed almost wholly of the mineral calcite. Other rocks have many minerals, and the specific minerals in a rock can vary widely. Some minerals, like quartz, mica or feldspar are general, while others have been found in only one or two locations worldwide. The vast majority of the rocks of the Earth's crust consist of quartz, feldspar, mica, chlorite, kaolin, calcite, epidote, olivine, augite, hornblende, magnetite, hematite, limonite and a few other minerals.Over half of the mineral species identified are so rare that they have only been found in a handful of samples, and many are known from only one or two small grains.
Commercially costly minerals and rocks are referred to as industrial minerals. Rocks from which minerals are mined for economic purposes are referred to as ores (the rocks and minerals that remain, after the desired mineral has been separated from the ore, are referred to as tailings).

Acid rain

Acid rain occurs when sulphur dioxide and nitrogen oxides are emitted into the atmosphere, undergo chemical transformations and are absorbed by water droplets in clouds. The droplets then fall to earth as rain, snow, mist, dry dust, hail, or sleet. This can add to the acidity of the soil, and affect the element balance of lakes and streams.The term "acid rain" is sometimes used more usually to include all forms of acid deposition - both wet deposition, where acidic gases and particles are removed by rain or other precipitation, and dry deposition removal of gases and particles to the Earth's surface in the absence of precipitation. Acid rain is defined as any type of precipitation with a pH that is abnormally low. Dissolved carbon dioxide dissociates to form weak carbonic acid giving a pH of approximately 5.6 at typical atmospheric concentrations of CO2. Therefore a pH of less than 5.6 has every so often been used as a definition of acid rain. However, natural sources of acidity mean that in remote areas, rain has a pH which is between 4.5 and 5.6 with an average value of 5.0 and so rain with a pH of less than 5 is a more appropriate definition. The US EPA says, "Acid rain is a serious environmental problem that affects large parts of the US and Canada" Acid rain accelerates weathering in carbonate rocks and accelerates building weathering. It also contributes to acidification of rivers, streams, and forest damage at high elevations. When the acid builds up in rivers and streams it can kill fish.

Historiography

Historiography has a number of associated meanings. It can refer to the history of historical learning, its methodology and practices (the history of history). It can also refer to a particular body of historical writing (for example, "medieval historiography during the 1960s" means "medieval history written during the 1960s"). Historiography can also be in use to mean historical theory or the study of past writing and memory. As a meta-level analysis of descriptions of the past, this third conception can relate to the first two in that the analysis usually focuses on the narratives, interpretations, worldview, use of evidence, or method of presentation of other historians.

Gardening

Gardening is the art of growing plants with the aim of crafting a purposeful landscape. Residential gardening most often takes place in or about a residence, in a space referred to as the garden. Although a garden naturally is located on the land near a residence, it may also be located in a roof, in an entrance, on a balcony, in a windowbox, or on a yard.
Gardening also takes place in non-residential green areas, such as parks, public or semi-public gardens (botanical gardens or zoological gardens), pleasure and theme parks, along transportation corridors, and around tourist attractions and hotels. In these situations, a staff of gardeners or groundskeepers maintains the gardens.
Indoor gardening is concerned with the increasing of houseplants within a residence or building, in a conservatory, or in a greenhouse. Indoor gardens are sometimes included as part of air conditioning or heating systems.
Water gardening is concerned with growing plants adapted to pools and ponds. Bog gardens are also considered a type of water garden. These all require extraordinary conditions and considerations. A simple water garden may consist simply of a tub containing the water and plant(s).
Container gardening is concerned with growing plants in any type of container either indoors or outdoors. Common containers are pots, hanging baskets, and planters. Container gardening is usually used in atriums and on balconies, patios, and roof tops.

Public transport

Public transport, public transportation, public travel or mass transit comprises all transport systems in which the passengers do not tour in their own vehicles. While it is generally taken to include rail and bus services, wider definitions would comprise scheduled airline services, ship, taxicab services etc. – any system that transports members of the universal public. A further restriction that is sometimes practical is that it must take place in shared vehicles that would bar taxis that are not shared-ride taxis.

Journalism Basics

Journalism is a concrete, professionally oriented major that involves gathering, interpreting, distilling, and other reporting information to the general audiences through a variety of media means. Journalism majors learn about every possible kind of Journalism (including magazine, newspaper, online journalism, photojournalism, broadcast journalism, and public relations).
That's not all, though. In addition to dedicated training in writing, editing, and reporting, Journalism wants a working knowledge of history, culture, and current events. You'll more than likely be required to take up a broad range of courses that runs the range from statistics to the hard sciences to economics to history. There would also be a lot of haughty talk about professional ethics and civic responsibility too - and you'll be tested on it. To top it all off, you'll perhaps work on the university newspaper or radio station, or possibly complete an internship with a magazine or a mass media conglomerate.

Color

It is the visual perceptual property corresponding in humans to the categories called red, yellow, white, etc. Color derives from the spectrum of light distribution of light energy versus wavelength interacting in the eye with the spectral sensitivities of the light receptors. Color categories and physical specifications of color are also associated with objects, materials, light sources, etc., based on their physical properties such as light absorption, reflection, or emission spectra.

Typically, only features of the composition of light that are detectable by humans wavelength spectrum from 400 nm to 700 nm, roughly are included, thereby objectively relating the psychological phenomenon of color to its physical specification. Since perception of color stems from the varying sensitivity of different types of cone cells in the retina to different parts of the spectrum, colors may be defined and quantified by the degree to which they stimulate these cells. These physical or physiological quantifications of color, however, do not fully explain the psychophysical perception of color appearance.

The science of color is sometimes called chromatics. It includes the perception of color by the human eye and brain, the origin of color in materials, color theory in art, and the physics of electromagnetic radiation in the visible range that is, what we commonly refer to simply as light.

Painting

Painting taken literally is the practice of applying color to a surface such as paper, canvas, wood, glass, or other. However, when used in an artistic sense, the term painting means the use of this activity in combination with drawing, composition and other aesthetic considerations in order to manifest the expressive and conceptual intention of the practitioner.
Painting is used as a mode of representing, documenting and expressing all the varied intents and subjects that are as numerous as there are practitioners of the craft. Paintings can be naturalistic and representational. photographic, abstract, be loaded with narrative content, symbolism, emotion or be political in nature. A large portion of the history of painting is dominated by spiritual motifs and ideas; sites of this kind of painting range from artwork depicting mythological figures on pottery to biblical scenes rendered on the interior walls and ceiling of The Sistine Chapel to depictions of the human body itself as a spiritual subject.

Health

Health is the practical and metabolic efficiency of an organism, at any moment in time, at both the cellular and global levels. All individual organisms, from the simplest to the most complex, vary among optimum health and zero health.

In the medical field, health is normally defined as an organism's ability to capably respond to challenges and effectively restore and sustain a "state of balance," known as homeostasis.

Another broadly accepted definition of health is that of the World Health Organization "WHO". It states that "health is a state of absolute physical, mental and social well-being and not just the absence of disease or infirmity". In more recent years, this statement has been customized to include the ability to lead a "socially and economically creative life." The WHO definition is not without criticism, as some dispute that health cannot be defined as a state at all, but must be seen as a process of continuous alteration to the changing demands of living and of the changing meanings we give to life. The WHO definition is therefore measured by many as an idealistic goal rather than a realistic intention.

An increasing measure of the health of populations is height, which is powerfully regulated by nutrition and health care, among other average of living and quality of life matters. The study of human growth, its regulators and its implications is known as auxology.

Clothing

Clothing is defined, in its broadest logic, as coverings for the torso and limbs as well as coverings for the hands, feet and head. Humans almost universally wear clothes, which are also known as dress, garments, attire, or apparel. People wear clothing for functional as well as for social reasons. Clothing protects the vulnerable nude human body from the extremes of weather, other features of our environment, and for safety reasons. But every article of clothing also carries a civilizing and social meaning.
People also decorate their bodies with structure or foundation, perfume, and other decoration they also cut, dye, and arrange the hair of their heads, faces, and bodies, and sometimes also mark their skin. All these decorations add to the overall effect and message of clothing, but do not constitute clothing per se.
Articles approved rather than damaged are normally counted as fashion garnishes rather than as clothing. Jewelry and spectacles are usually counted as accessories as well, even though in ordinary speech these items are described as being worn rather than carried.

Lighthouse of Alexandria

The Pharos of Alexandria was a tower built in the 3rd century BC on the island of Pharos in Alexandria, Egypt to supply as that port's landmark, and later, its lighthouse.

With a height variously projected at between 115 and 135 meters it was among the tallest man-made structures on Earth for many centuries, and was identified as one of the Seven Wonders of the World by traditional writers.

It ceased working and was largely destroyed as a result of an earthquake in 1375; some of its remains were found on the floor of Alexandria's Eastern Harbour by divers in 1994. More of the residues have subsequently been exposed by satellite imaging.

His design of minarets in many early Islamic mosques many centuries later followed a similar three-stage design to that of the Pharos, attesting to the building's broader architectural authority.

Computer

A computer is a device for manipulating data according to a list of instructions. A list of computer instructions planned to perform some task is known as a program. When programs are contained in storage that may be easily customized by the computer itself, the device is said to have Von Neumann architecture. The ability to execute stored programs that is, programmability makes computers extremely versatile and distinguishes them from calculators. The Church Turing thesis is a mathematical statement of this versatility: Any computer with a certain minimum potential is, in principle, capable of performing the same tasks that any other computer can execute. Therefore, computers with potential and complexity ranging from that of a personal digital assistant to a supercomputer are all able to perform the same computational tasks so long as time and storage capacity are not considerations.
Computers take several physical forms. Early electronic computers were the mass of a large room, consuming as much power as several hundred modern personal computers. Today, computers can be made little enough to fit into a wrist watch and powered from a watch battery.

Construction

Under project architecture and civil engineering, construction means building or assembly of any infrastructure on a site or sites. Though this may be thought of as a single activity, in fact construction is a feat of multitasking. Normally the job is managed by the construction manager, supervised by the project director, design engineer or project architect. While these people work in offices, every construction project requires a large number of laborers, carpenters, and other skilled tradesmen to complete the physical job of construction.
For the successful execution of a project functional planning is essential. Those concerned with the design and execution of the infrastructure in question must consider the environmental impact of the job, the unbeaten scheduling, budgeting, site safety, availability of materials, logistics, inconvenience to the public caused by construction delays, preparing tender documents, etc.

Deregulation is the de-emphasis of governmental oversight of actions in the private sector. It was known that regulation is where the government controls convinced aspects of the private sector, led to a monopolistic state amongst businesses and it was no longer viewed as productive with the modern growth of the economy.

Research Animal Rights

The frantic and the high tech world we live in today have progressed through a series of life altering changes throughout the last couple of centuries. Nearly all of this progress can be traced back to the advancement of technology. The Technology has allowed humans to do everything from flying an airplane to creating clones. Ahead with the economical and educational benefits of technology, medical advances have soared. This has been raised by one of the most debated and biggest moral questions: “is it really necessary to take the lives of animals in the name of science and for the betterment of humanity?” While some social groups think animals should have the same rights as humans, the undeniable truth is that animal research is too important to all species in our world to be stopped.
Through the entire 20th century medicine as experienced phenomenal success and this can be attributed mainly to technology and the brilliant minds that applied it to medicine. Anyway, the advancement of medicine and human health has not come without cost. To find new and more efficient forms of treatments, scientist sacrificed many animals in their testing and research.
Many more changes are needed in our current methods of research. For the human beings this topic of death is still being debated, but animals are put to sleep every day when their owner or veterinarian decides the quality of the animal’s life will be too low for it to continue to survive.

Essentials of Healthy life – Cleanliness a brief review

Health is wealth so preserve it. Life is short so use it in the right way. Cleanliness merely fits with the apt meaning of being free from dirt, dust, germs and bad smells. A recent shift has now taken place to recognise that ‘germs’ may play a major role in our immune systems. So experts say washing hands frequently, specially when in an environment of many people with infections and diseases. Washing is one of the best way to achieve cleanliness.Have a brief overlook on the following issue to be aware of how to keep one self clean.

A step way process regarding cleanliness of hands is given below:
· Use warm water
· But avoid scorching your hands.
· Use anti-bacterial soap or hand wash.
· Wash between fingers and use paper towels to wipe off.
Washing of hands has to be followed
· Before eating
· After eating
· After using the toilet
· After playing outdoor games
· After attending to a sick person
· After blowing nose, coughing, or sneezing; and after handling pets.
The proverb "Cleanliness is next to Godliness," a common phrase that describes humanity's high opinion of being clean. Purposes of cleanliness include health, beauty and to avoid the spreading of germs .If your hands have any kind of skin cut or infection, wash hands with an anti bacterial soap. Thoroughly wash with hot, soapy water all surfaces that come in contact with raw meat, poultry, fish, and eggs before moving on to the next step in food preparation. Consider using paper towels to clean kitchen surfaces.
Keep pets, household cleaners, and other chemicals away from food and surfaces used for food. Along with removing any old food or dirty water, it’s a very good practice to clean the bowls or containers that the food and water are in, ever Hygienic practices—such as frequent hand washing or the use of boiled (and thus sterilized) water have a profound impact on reducing the spread of disease. This is because they kill or remove disease-causing microbes (germs) in the immediate surroundings. For instance, washing one's hands after using the toilet and before handling food reduces the chance of spreading E. coli bacteria and Hepatitis A, both of which are spread from fecal contamination of food.
Personal cleanliness:
· Daily washing of the body and hair.
· More frequent washing of hands and face.
· Oral hygiene—Daily brushing teeth.
· Cleaning of the clothes and living area.
· Use of bandaging and dressing of wounds.
· Not touching animals before eating.
· avoidance of unhygienic people.
· Holding a tissue in your hand when coughing or sneezeing.
· Suppression of habits such as spitting or nose-picking.
· Washing hands before eating.
· Not licking fingers before picking up sheets of paper.
· Cut finger nails and toe nails.

Hazards of Solar flare

Solar flares and associated Coronal Mass Ejections (CMEs) strongly influence our local space weather. They produce streams of highly energetic particles in the solar wind and the Earth's magnetosphere that can present radiation hazards to spacecraft and astronauts. The soft X-ray flux of X class flares increases the ionisation of the upper atmosphere, which can interfere with short-wave radio communication, and can increase the drag on low orbiting satellites, leading to orbital decay. Energetic particles in the magnetosphere contribute to the aurora borealis and aurora australis.

Solar flares release a cascade of high energy particles known as a proton storm. Protons can pass through the human body, doing biochemical damage. Most proton storms take two or more hours from the time of visual detection to reach Earth. A solar flare on January 20, 2005 released the highest concentration of protons ever directly measured, taking only 15 minutes after observation to reach Earth.

The radiation risk posed by solar flares and CMEs is one of the major concerns in discussions of manned missions to Mars or to the moon. Some kind of physical or magnetic shielding would be required to protect the astronauts. Originally it was thought that astronauts would have two hours time to get into shelter. Based on the January 20 event, they may have as little as 15 minutes to do so.

Factors such as reduction of average interest rate, reduced to one credit payment from multiple creditors, reduction of past interest or penalty charges, obtaining a payment plan as per the capability of an individual and becoming debt free individual at a faster rate.
Advantages1.

So an individual may choose this option to reduce his interest rate.2. Reduction to one credit payment:An individual may use many credit cards and pay his bills for all the credit cards. This may need a good management technique depending up on the number of cards in use. If you use more number of credit cards then the planning need to be done more appropriately and executed timely where as if you have one credit card your job is done in a way simple and easily executable. One hence opts to shift from multiple loan payments to one loan payment program replacing all the rest.3. Reduction of past interest or penalty charges:One opting for debt consolidation may go for reduction of past interest or penalty charges paid for the borrowed amount under certain options. Options include high interest rate or penalty charges placed for the credited amount, when the total amount paid in the history till date exceeds the borrowed amount, or if it is a very long duration payment program going for 5 yrs or above. Under each case stated one can reduce the past interest and penalty charges or sometimes even eliminate those and pay only the amount borrowed.4. Obtaining a payment plan:This payment plan is given to the consumer analyzing the capability of an individual by thoroughly going through the personal needs of an individual, his responsibilities etc after which the debt consolidator restructures the existing plans taken by the consumer.5. Becoming debt free at a faster rate:Taking debt consolidation program relieves a person from debts at a faster rate than the usual time, which is required to come out of the debt. Following the plans given by a debt consolidator and proper execution of the plan will surely make an individual debt free and obtain high credit scores.

2. You tend to use your credit cards again since you had paid back the credit amount through another loan. Hence the usage of credit cards ads up to your debts ending up in bankruptcy.

Euro

The euro (symbol: €; banking code: EUR) is the currency of twelve European Union member states: Austria, Belgium, Finland, France, Germany, Greece, the Republic of Ireland, Italy, Luxembourg, the Netherlands, Portugal, and Spain, collectively known as the Eurozone. The euro is the result of the most significant monetary reform in Europe since the Roman Empire. Although the euro can be seen simply as a mechanism for perfecting the Single European Market, facilitating free trade among the members of the Eurozone, it is also regarded by its founders as a key part of the project of European political integration.
Monaco, San Marino, and the Vatican City, which formerly used the French franc or the Italian lira as their currency, now use the euro as their currency and are licensed to mint their own euro coins in small amounts, even though they are not EU states. The euro is also used for payment of debt in other European non-EU jurisdictions such as Montenegro, Kosovo and Andorra.
The euro is administered by the European System of Central Banks (ESCB), composed of the European Central Bank (ECB) and the Eurozone central banks operating in member states. The ECB (headquartered in Frankfurt am Main, Germany) has sole authority to set monetary policy; the other members of the ESCB participate in the printing, minting and distribution of notes and coins, and the operation of the Eurozone payment system. florida discount health care san fransisco shuttletours cheap spanish holiday

The Gift of Teaching

The Gift of Teaching

Parents are truly the first teachers that their children encounter. They are there in those very vital formative initial years of life, when the most basic functions and abilities are taught and practiced. Values, behavior, and living skills are in the process of forming and the child's environment and the examples of parents weight so heavily in this very delicate balance of becoming a fully functioning adult. When a child matures and reaches the age of attending school, something magical takes place. Interests expand, social skills are just beginning to blossom, and imagination and creativity are being explored and tested. Whether a child attends a home school or a local school (public or private) the next vital components in development are being put to the "max." Science, math, language, history, and all the other subjects that make up a curriculum are vying for the attention and abilities of the child. From printing their name for the first time to solving a complicated math process all add to the qualities and essence that will evolve, expand, and let them become a wonderful asset to the entire world. No longer is it correct to assume that this boy/girl should only fit in comfortably and capably in the goegraphical area he/she calls home, but with the advance of computers and other technological achievements, this child is most definitely a citizen of every other continent and country, and in the future, possibly of other galaxies and planets. With the approach of a new upcoming school year, may all the teachers (parents, educators, neighbors, writers, etc.) brace themselves for the wonderful task at hand. To further the education of any child is the richest, most rewarding experience in life. There can be no more noble undertaking than to lead a child to investigating, challenging themselves and their surroundings, attempting, and succeeding at skills and subjects that will let this child open doors to his/her future. From a parent giving an example of honesty, a neighbor pointing out the beauty of a newly born kitten, a teacher who brings a subject or book to life, and a writer who paints a "word" picture of a sunset, all these individuals play such an important role in the formation and the future of this child. When a child's environment is rich with caring, loving people who want only to bring the sunshine of knowledge and capability into this child's world, then the possibilities are endless, the potential without limit. A book contains written words, a fanciful tale, the recorded experiences of an individual, or the peculiarities of a location, but a "teacher" can infuse life and reality into the material. History becomes a wealth of evolvement and ancestry, science is a world of not-yet-discovered solutions, and the realm of language is transformed into building blocks to reach the stars.

Free Tips For Your Child's Success

Getting free tips for a child's success is something mostparents/guardians are interested in. Most want their child'sacademic growth to improve every school year. Most sincerelycare. Unfortunately some don't, but that's a completely differentarticle. For now, I want to focus on improving the readingabilities of our children immediately.This summer is flying by and soon our children will be back inthe classroom with the eager teachers and their fellowclassmates. My concern as an educator, with over twenty years ofinvaluable experience, is the loss of reading and comprehensionskills over the summer months simply due to lack of reading. Children need to read in order to keep up their skills. Theymust read on a consistent basis to not only maintain but to alsoimprove their skills. Just as any skill or talent, if it isn'tused, it will slowly diminish. Do we really need our children'sreading abilities to begin to waste away as they enjoy the summermonths? I don't think so. Our society can't afford this tohappen either.I frequently compare reading skills to that of a runner's skills. A person that wishes to maintain or improve his or her runningability must run almost on a daily basis. What takes much timeand effort to achieve however, can be very quickly lost if thatrunner takes some time off. Basically, to maintain the skills,the runner needs to run on a consistent basis. This is exactlywhat we are looking to achieve with our children and theirreading skills. We want them to maintain and even improve theirskills. This can be accomplished by reading consistently. Perhaps not every day, but consistently.OK, now I have opened up a very large can of worms, haven't I? Don't get discouraged. Many questions do arise, all of which canbe answered. Questions such as: How much time should my childspend reading? How many days a week? What should my child read? The most frequent question: What can I do to get my child to sitand read when he or she can be rather resistant to the idea? Contact me at mailto:frankw@eticomm.net and I will respond.

Kids and Computing

Kids and Computing

Computers can do much more than help children with their schoolwork - they allow them to acquire valuable knowledge and skills for their future careers.Buying a great multimedia home PC can kick-start your kids into a great career, and not just in accountancy. The new PC industry is looking for artists, writers, storytellers, publishers, games players and designers - but they need to start early.According to Plato, the most effective kind of education is that a child should play among lovely things. While he probably wasn't thinking digitally at the time, with the emergence of powerful and affordable multimedia PCs, children can now play among lovely things and at the same time acquire valuable knowledge and skills that will serve them well in whatever career or profession they may decide to pursue.Today, most children take computers like ducks to water. Even the youngest seem to be alarming clever at setting up and operating all sort of gadgets. Whatever they're using a popular game console or any of the other ubiquitous home or arcade systems, technology seems to be more naturally comprehensible to the average child than it is to the average parent or teacher.With an increasingly large percentage of children living in households with a computer of some sort, in many ways they're now becoming just another home appliance. But for parents who want to help their children at home/school, the apparent labyrinth of technological options can appear depressingly daunting.It's now possible to get great job in computers that isn't about science, maths programming or accountancy. Increasingly, `humanity-based' skills are often perceived as more valuable and computers can get you into a whole new range of professions evolving around games production, multimedia, digital video or publishing on the Internet. Within these, and even more traditional professions - such as journalism, film, television, publishing, advertising, design and music - computers and digital technology have become widespread. And there are probably very few jobs or professions in the future that won't require some degree of computer literacy.Ironically, the digital revolution is creating a market not for narrow specialists, but for `renaissance men and women' who have a broad-based education and a wider skill set that will allow them to change careers and move from field to field with an ease and efficiency that was unimaginable in previous generations. Today, perhaps more than any other time in recent history, education needs to be focused on learning how to learn and on development of study skills that will allow children to acquire the information they need as and when they need it.Remember, helping your child with a computer at home isn't exclusively about using so called `educational software' like they do at school to teach spelling, maths or geography. Parents can often provide more help by encouraging their children to simply use computers more actively and creatively as they are, or will be, used in the real world and to develop creative study and research skills that will complement and enhance their learning experience at school. To do that, you need to give your kids their best chance possible by getting them a really good multimedia PC.But to prepare your children for the future, you need more than hardware and software. The most important thing is to think about what they do with the PC and what you can do to help. Don't worry about starting children too early. As soon as they can control their hands, children will find things to do with a computer. It's not unusual to see three and four-year old happily working with paint programs and even creating and saving files. In many respects, having a computer at home can help older children with their school work in nearly every subject, just as having books at home helps them with reading and research. And because of its increasingly multimedia and interactive capabilities, a PC can provide a creative focus or outlet for even difficult children with no apparent interest in traditional education.This concern about `giving the kids the best' for their education is an emotion that computer manufacturers are more than happy to exploit, with many of them offering PCs that are hyped as the `ideal tool for education'. Then, of course, there's the fact that more than a few parents use their kid's education as a way to justify buying a PC so they can play Doom. But the hardware you buy is only half the story and where home computers are concerned, the bundled software is just as important as the hardware.It used to be that computer manufacturers interpreted the phrase `for educational use' as meaning `last year's leftover stock with a copy of Encarta chunked in'. However, as the home market has boomed, some manufacturers have come to realize that education has its own needs, and are producing systems that combine powerful hardware with a good range of bundled software with an obvious educational or informative bent.

Distiller Water Filters

Water distillers use electricity to heat tap water to boiling point. Generally the Impurities are left in the container and the purified contents go back to a clean container. They need a higher level of efficiency and cannot give immediate supply, because the boiling process must be over before water is present. There are a number of reports in that distilled water is not fit for health because it takes away nutrients from the body, being the most 'unnatural' of water.

Ionized Water Filters
These are generally filtered using an acid and an alkaline. They run between the positive and the negative ends of the electrodes and get the charged and acidic water. They are formed using 70% alkaline water and 30% Acid water. Alkaline and Acidic waters have unusual properties and benefits, but anyway their respective uses could not be more different.

Back flush Water Filters
They are costlier compared to charcoal filter units, but justify this by their claims of longevity. They are highly durable and efficient.

Painting Mediums

Paint and paintings materials differ depending up on the place where it is to be painted whether it is an interior painting or exterior. Interior paintings basically use materials such as oil paint, water colors, wooden board, fabric etc where as exterior paintings involves using water resistant base and mediums.

orlando villas

Sitting here in early August gazing at the grey English skies makes me long to
return to sunnier climates. My thoughts turn firmly to Florida and I find myself
browsing for Orlando villas to rent on orlando
villas
.

I remember my last trip as if it was only yesterday, especially my close encounter
whilst absorbing one of Central Florida’s natural attractions, the swamps.


Although we were staying in an Orlando vacation rental home which are mainly
filled with out-of-state tourists, I bumped into a local called Carl who was
working for www.wireitright.com who suggested that our families meet up one
Sunday afternoon at a country park about 30 miles North West of Orlando. Eager
to see more of Florida’s natural beauty, sure enough one week later we
found ourselves heading up to Wekiva. We met with our new friends and decided
to rent some canoes and head north upriver.


The shallow river was fairly dense with fallen trees and navigating them was
difficult. Whilst rowing with one ore and two you kids was hard-work heading
up-stream, the current made it fairly easy to control the canoe and navigate
the tight corners. As we passed one particularly hairy tight spot, a 7ft alligator
was clearly visible. The kids, aged 4 and 5, were already on the lookout for
alligators and they fell very silent as we passed.


Eventually we found a sand island in the middle of the river and stopped for
refreshment. My 4 year old picked up a stick that was floating down-stream.
When he asked me why the stick was moving I shouted to him to drop it, fortunately
it looked like it was just a water snake.


I need some excitement in my life again, time to fins another Florida vacation
villa for rent on www.fabvillas.com. If I can, I’ll try to stay at Emerald
Retreat again as it was a wonderful villa with everything that I could have
dreamed of, details can be found at www.emeraldislandflorida.com

Internet

An internet is a more general term informally used to describe any set of interconnected computer networks that are connected by internetworking.
The Internet, or simply the Net, is the publicly accessible worldwide system of interconnected computer networks that transmit data by packet switching using a standardized Internet Protocol (IP) and many other protocols. It is made up of thousands of smaller commercial, academic, domestic and government networks. It carries various information and services, such as electronic mail, online chat and the interlinked web pages and other documents of the World Wide Web.
Creation of the InternetDuring the 1950s, communications researchers realized that there was a need to allow general communication between users of various computers and communications networks. This led to research into decentralized networks, queuing theory, and packet switching. The development of ARPANET in the United States would lead to technical developments that made it the center point for the development of the Internet.
The first TCP/IP wide area network was operational in 1984 when the National Science Foundation's (NSF) constructed a university network backbone that would later become the NSFNet. It was then followed by the opening of the network to commercial interests in 1995. Important seperate networks that have successfully entered the Internet include Usenet, Bitnet and the various commercial and educational X.25 networks such as Compuserve and JANET.
The collective network gained a public face in the 1990s. In August 1991 Tim Berners-Lee publicized his new World Wide Web project, two years after he had begun creating HTML, HTTP and the first few web pages at CERN in Switzerland. In 1993 the Mosaic web browser version 1.0 was released, and by late 1994 there was growing public interest in the previously academic/technical Internet. By 1996 the word "Internet" was common public currency, but it referred almost entirely to the World Wide Web.
Meanwhile, over the course of the decade, the Internet successfully accommodated the majority of previously existing public computer networks (although some networks such as FidoNet have remained separate). This growth is often attributed to the lack of central administration, which allows organic growth of the network, as well as the non-proprietary nature of the Internet protocols, which encourages vendor interoperability and prevents any one company from exerting too much control over the network.
Today's Internet Apart from the incredibly complex physical connections that make up its infrastructure, the Internet is held together by bi- or multi-lateral commercial contracts (for example peering agreements) and by technical specifications or protocols that describe how to exchange data over the network.
Unlike older communications systems, the Internet protocol suite was deliberately designed to be independent of the underlying physical medium. Any communications network, wired or wireless, that can carry two-way digital data can carry Internet traffic. Thus, Internet packets flow through wired networks like copper wire, coaxial cable, and fiber optic; and through wireless networks like Wi-Fi. Together, all these networks, sharing the same high-level protocols, form the Internet.
The Internet protocols originate from discussions within the Internet Engineering Task Force (IETF) and its working groups, which are open to public participation and review. These committees produce documents that are known as Request for Comments documents (RFCs). Some RFCs are raised to the status of Internet Standard by the Internet Architecture Board (IAB).
Some of the most used protocols in the Internet protocol suite are IP, TCP, UDP, DNS, PPP, SLIP, ICMP, POP3, IMAP, SMTP, HTTP, HTTPS, SSH, Telnet, FTP, LDAP, SSL, and TLS.
Some of the popular services on the Internet that make use of these protocols are e-mail, Usenet newsgroups, file sharing, Instant Messenger, the World Wide Web, Gopher, session access, WAIS, finger, IRC, MUDs, and MUSHs. Of these, e-mail and the World Wide Web are clearly the most used, and many other services are built upon them, such as mailing lists and web logs. The Internet makes it possible to provide real-time services such as Internet radio and webcasts that can be accessed from anywhere in the world.
Some other popular services of the Internet were not created this way, but were originally based on proprietary systems. These include IRC, ICQ, AIM, and Gnutella.
There have been many analyses of the Internet and its structure. For example, it has been determined that the Internet IP routing structure and hypertext links of the World Wide Web are examples of scale-free networks.
Similar to how the commercial Internet providers connect via Internet exchange points, research networks tend to interconnect into large subnetworks such as:
GEANT Internet2 GLORIAD These in turn are built around relatively smaller networks. See also the list of academic computer network organizations
In network schematic diagrams, the Internet is often represented by a cloud symbol, into and out of which network communications can pass.
