Internet concept:
- A big word that has a broad and extended meaning and meaning in the world of technology, which is a global network through which data and information are exchanged between computers all over the world.
- Therefore, it is considered an infrastructure that is transferred across the continents of the world among themselves, whether at the level of the individual or at the level of the local, regional and international institution.
Description of the Internet:
- It is a huge spider network that contains a very, very large number of networks through wireless links, copper wires and optical fibers.
- The most common and used examples on the Internet are: e-mail, web pages, instant messaging, and many others; It is a necessary need for the labor market, education, health, commerce, and many, many other areas.
Internet history:
- Let us, dear reader, speak, if only in a few words, about the history of the emergence of the Internet, which was the beginning of its appearance in 1969, in the United States of America.
- The US Department of Defense created a communications network that would continue to operate in the event their country was subjected to a nuclear attack during the war during that period.
- The Internet is a simple idea represented in a communications network that does not have a main center to control it.
- The so-called advanced research projects agency network appeared, which is the acronym of the advanced research projects agency network, and it is a project on which the US Department of Defense relies entirely on its communication through four computers linked to each other by telephone wires connected to research centers It is affiliated with American universities, which helped to create this network, and whose most successful idea is the modem that was invented by the Bell Company in 1958, a tool that allows the transmission of digital data over the telephone line.
- ARPANET did not stop there. Rather, the US Department of Defense made this network available for the use of universities, research centers, and scientific organizations to develop it into an effective communication system; In 1971, the number of computers connected to each other through the ARPANET increased, and this year was marked by sending Ray Tomlinson, the first e-mail in the world, and this use of the network expanded until 1973, when Britain and Norway connected to the Internet through one computer between them, and in 1979 the students expanded The term “Newsgroups” appeared, which is a special forum for discussing their research, and the word “internet” actually appeared in 1982, which is the Internet protocol package, so the US Department of Defense changed its dependence on the protocol it was working on from ncp to a different protocol package from the internet (dns) and it was This is in 1983.
- In the same year, the ARPANET network was divided into two networks of different use, the first is ARPANET, which is used for civilian purposes, and the second is Melnet, which is for military uses.
Stages Department:
The number of computers in use increased from 1,000 computers in 1984 to 100,000 computers in 1989, and with this number the word ARPANET disappeared in 1990, and the word Internet became popular, and it became a spider.The term (world wide web), i.e. www, appeared in the year 1991 for browsing the Internet, and the Internet developed over these years, and it became a very urgent and necessary need that cannot be dispensed with, even for a moment.
