The Internet -A short History
Internet often described a "network networks". The
term very suitable, there no one authority "owns"
or administers Internet would be impossible draw a map of
Internet. There no single list millions users with
access Internet. Instead, Internet can be looked upon a
sort confederation, a worldwide collection national, regional,
campus corporate networks.
The roots Internet lie a collection government computer networks were developed 1970s has grown since as different organizations have realized great advantages being connected. They started with a network called Arpanet was sponsored by United States Department Defense. This was intended test methods making computer networks survive military attack. By dispersing network over a wide area, using a web connections between computers, a system could continue functioning even when portions were destroyed, by redirecting communications through the remaining portions network.
The original Arpanet has long since been expanded replaced today its descendants form global backbone what we call Internet. The National Science Foundation helped tremendously with progression Internet when realized that could save money by creating several super computer centers connected a network, so that researchers, major universities example, could connect them.
Nobody owns Internet just nobody owns world's telephone network. Each component owned by somebody, but network a whole not owned by one single person. It a system that brought together by mutual interest. Telephone companies from all over world get together decide best way "network" should function. They decided country codes, billing international calls, who pays for laying cables technical details of connection from country country.
Over past decade Internet has grown tremendously with all sorts organizations becoming involved, each connecting its own network, with its own particular configuration hardware software. Therein lies a problem. It a problem planning resulting way the network grew. If cities are compared, for example, some are a mesh of intertwining roads where others are laid out a grid. Some cities have been planned, other cities just grew. The Internet was not really planned just grew, with there being no single company that decides what network should look like makes difficult when you decide you would like use Internet. The Internet governed by consensus, by diverse organization getting together make all work. When first attempting use Internet, can be like attempting to navigate your way around a city without a map or guide book. It can still be interesting but you may not find what you are looking for and become lost.
As nobody actually owns Internet, ISOC (the Internet Society) elect a "council elders". This council known the Internet Architecture board (IAB) who agree how network will function. They turn are advised by Internet Engineering Task Force (IETF) that study technical problems.
A revolution taking place. It started quietly has grown to involve much world. The Internet, a communication system is revolutionizing way we work play. People may feel like the Internet will not effect them, but will or has already. In fact the Internet, if has not already done so, will probably effect almost everyone very soon.
The Internet currently reaches millions people over 61 countries.
Nearly all colleges and universities have access Internet.
The U.S. military has been using Internet technology for over a decade
Scientists have been using Internet since 1980.
The government Internet, along with major political parties.
Business has begun selling goods and services over Internet through electronic commerce enabled Web sites.
The most common assessment Internet's significance measures the number computers that connect it. However, conventional computer connections tell only part story. The Internet reaches ships at sea, planes air and mobile vehicles land. Private companies provide access Internet services through telephone system, making possible reach Internet from any home or office that has a telephone. To assess impact Internet, question can be asked, "What has affected?" The answer is, Almost everything. So question are you ready for it?
