Technically, the Internet is a worldwide network that links computer networks between them. It is somehow the network all networks. Computers of all kinds can communicate and exchange information, because they have a common communication protocol TCP/IP (Transmission Control Protocol/Internet Protocol) use.
The Internet can also be described as a community generated its own rules: "netiquette". In the culture of the Internet, information is considered as a free resource that does not have to support the restrictions. Everyone should be able to tell what he wants with the sensors itself rather than the rules set forth by the Government. Electronic democracy where all are free and responsible somehow.
There are four main reasons for the success of the Internet: a unique address, TCP/IP protocols, universal basic services at extremely low costs of communication.
The unique global address: solo @ lieu
IP protocol set up each computer a unique address on a 32 bit (128-bit soon) that is usually written in the form of four 8-bit numbers written in decimal and separated by periods: 194.2.94.60. To facilitate the work, these addresses are written in symbolic form is also known for individual email: @ lieu.
The Tcp/ip Protocol
TCP/IP Protocol by success is the universality and simplicity. The TCP protocol is developed under the auspices of the DoD (Department of Defense State-United Kingdom), although there is a certain vendor or system. This Protocol, related to UNIX to debut that promote implementation, now available on all kinds of computers and a total of interoperabillite different between providers to offer. It should be noted that this interoperability with control through experiments, while the Committee for Standardisation (ISO) has been defeated.
While most network protocols offer a high level of service (treatment, of routing, and flows for example), the TCP protocol does nothing and leave the responsibility of the user. For example, the protocol guarantees the return of the packet, or even the order of routing. The result is a very simple network install with good performance. What may be considered a weakness when the computer a little stronger, a advantage today. The protocol only uses a fraction of the power of modern computers. Infrastructure networks have just switching functions. This is independent of the application, and provides you in support of different file transfer or applications such as video conferencing.
The basic universal service
The basic service provided by TCP/IP contributed to the success of the Internet. Of course it was the first service of electronic mail (E-mail), which thanks to the unique address (individual @ lieu) allows to communicate much simpler than with the phone. The most famous service is the terminal emulation (Telnet, which allows you to connect remotely to the computer type), newsgroups (Usenet), file transfer (FTP), internet relay chat (IRC).
Communication costs are very low
A network with which a service or billing, cost of operation down on one of the installation of the switch "router" and stay connect this router. Fixed costs are divided between the user, depends on the flow of asked. Any user can install depends on the level of service required of computer control, name, or access control. This explains the reason why these networks can support the rapid growth. Each user adds additional processing capacity is required. This scheme, unlike the usual practice of telecommunications operators, will result in the year which comes from the great turmoil in the world of telecommunications.
World Wide Web (WWW)
With a worldwide set of interconnected computers and can be accessed in less than a second, researchers at CERN in Geneva provided for a system that is designed to simplify access to information. They built a hypertext system for associating text and multimedia data using a set of interconnected computers as a single universal database. Each document has a unique global address (URL Universal Resource Locator), which can be referenced in a document. The success of wilting. In 1996 there were already over 30 million pages with General information that is referenced in research such as Yahoo, Lycos or Alta vista system.
