Internet
The internet is a collection of electronic computers are connected to each other and the public across the world to exchange information and share information. (Estimated at more than 3 million computers).
In the seventies began to universities, companies and government organizations using computer networks-mail on a large scale and the Internet began to emerge as a result of linking these networks with each other and the actual beginning was in the United States Department of Defense.
People organizations, companies and even individuals develop information on the Internet that can be accessed from any computer connected to the Internet. This information takes various forms, including reading and visual and audio.
Of the most popular Internet services are the e-mail Email and the World Wide Web, which shortened to WWW and file sharing service File Transfer Protocol, which shortened to FTP and the other services available, such as gradually widening search services and newsgroups Newsgroups.
History of the Internet
Internet began in 1969 as a research overseen by the Agency ARPA (Advanced Research Projects Agency) in the Department of Defense in the United States of America in cooperation with some contractors, universities, called the first name of ARPANET.
The objective was to study the possibility of developing communication network can survive a nuclear attack and that by securing a number of ways to transfer information if the destruction was part of the network is secured through the Contact section remaining.
ARPANET transformed quickly from the research project and to the means of communication and services used in the e-mail, discussion groups and file sharing. Network size gradually in creased and in 1979 Born T. The Usenet (and is a large network of discussion groups) and taking the number of universities connected to the Internet is increasing gradually.
Other networks began to appear gradually, such as BITNET and CSNET, but suffered from the problem of communicating with each other it was not possible to exchange information between these different networks to use different ways to contact. And in 1983 was to develop a system address is a standard TCP / IP and all began to use separate networks which led to the formation of a large network as a result of contact with these networks and the Internet have emerged.
At the very beginning there were three ways to obtain information from the network. Two of these were the roads were used to search for specific files from a file located on one computer and two Archie and WAIS Gopher , The third method was used to navigate through the files using the menu system, but do not provide service to search for files.
By this time, Internet users to computer experts because of its reliance on text in the presentation of information and was not in widespread use in homes.
The WWW
The idea of the WWW of the detective the European particle physics (CERN (The European Laboratory for Particle Physics, which was in need of an easy way to follow up the documents and information available to them so that can be accessed and updated. And is Mr. Tim Burner Lee who had previous experience of texts, divergent hypertext is the inventor of the Web, the project was implemented in 1992.
Was developed many ways to review the documents from WWW ,Mosaic was the most successful program developed by Mr. Marc Andersen of (NCSA (National Center for Supercomputing Applications, which was a step that brought the Internet into what it is.
How the Internet Works:
Internet Composed of a gathering of local computer networks, many of which are different in Onoaha of government networks to large networks, medium and small size. These networks are physically connected by many wires for data transmission.
In order to talk with one of these computers have been developing a set of rules called protocols mission to make the exchange of information standard process regardless of the system used in the party's messengers, or future.
