History of the Internet

Internet emerged as a result of Erbantalve project was launched in 1969, a project of the U.S. Department of Defense. This project was established to assist the U.S. Army through the computer network linking universities and research institutions to exploit the optimal computational capabilities of computers available.

In the first of January 1983 and replaced the United States Department of Defense Protocol) NCP in force in the network and replaced it Bmeevaq package Moafik (protocols) the Internet. Of the things that contributed to the growth of the network is to link the "National Science Foundation" Universities United States to each other, which facilitated the process of communication between university students and exchange of electronic messages and information, to enter the universities to the grid, took the network in the expansion and progress and taken it college students contribute their knowledge and saw the light browser "Mosaic", and the researcher "Gopher" and "Archie," but rather that the giant company, "Netscape" is originally from the efforts of the students before they adopted the mind of trade and lead them to what it later. engineers Ahapkh (the Internet) are a factor in the success of the network where that the public and open for all to give any opinion.

In 1993, the National Center for supercomputing applications at the University of Illinois has released version 1.0 of the MOSAIC "Mosaic", and by late 1994 there was a marked increase in the public interest in what was formerly paid to academics only. And by 1996 became Ahapkh use of the word has become common, and therefore, it was a cause of confusion in the use of the word Internet as a reference to the World Wide Web the Web.

During the nineties, it was estimated that Ahapkh has increased by 100% annually, with a brief period of explosive growth in 1996 and 1997. This growth is often due to the lack of central administration, which allows organic growth of the network, and also because of the property open to Moafik (protocols), the Internet, which encourages individuals and companies to develop Systems and sold it also prevents one company from exercising too much control over the network .

Web page can contain almost a combination of computer data, including photographs, graphics, audio, text, video, multimedia and interactive content including games and more.
[Edit] remote access
Internet allows computer users to communicate with other computers and servers information easily, regardless of their position in the world. This process is known to enter tele.
