The history of the Internet begins at the endthe fifties, when the second generation of computers was already in operation in the world. The external international relations of the leading world powers of the USSR and the US pushed for new research, necessary to protect and transmit information in a reliable way.
The US Department of Defensedevelopment of computer networks, from which the history of the development of the Internet began. Scientists from four renowned American universities took an active part in them. Their computers connected in 1969 ARPANET - the first computer network.
ARPANET began to be quickly used not onlymilitary, but also specialists in various fields of science. The first server appeared in the University of California (Los Angeles), the computer had a memory capacity of 24 KB. The first communication session took place in October 1969 with the Research Institute in Stanford, which was conducted by Charlie Kline and Bill Duvall.
In 1971, it was possible to sende-mail, because a special program was developed. In the future, the history of e-mail development was pushed by the desire of users to expand the horizons of communication.
A year later ARPANET became international, connecting through the telephone cable to Great Britain and Norway. In the seventies the first computer network was used mainly for sending mail.
In 1983, ARPANET was entrenched in the term Internet, and in the next year there is a system of domain names.
The history of the development of the Internet continuedOther networks that are built on data transfer protocols. A special role was played in this process by John Postel, who developed and standardized several network protocols: IP, ICMP, TCP, UDP, Telnet, FTP, DNS.
In 1984, the inter-university network NSFNet appeared, including other small networks, to which about ten thousand computers were connected during the year.
1988 was the year of the development of a chat, a protocol that allowed real-time communication.
In the late eighties, the history of developmentInternet has again acquired new names. Tim Berners-Lee, a British scientist who developed the HTTP protocol, the HTML language, URI identifiers, proposed in 1989 the concept of the World Wide Web (WWW).
In 1990, the first computer network left the Internet arena, and the World Wide Web by 1995 became the main provider of information on the Internet.
Now the world is not conceivable without the Internet. Finding useful information, shopping, business, entertainment - it is difficult to list all the possibilities of a global network.
The history of creating e-mail is not lessinteresting than the history of the Internet. Back in 1965, Tom Van Vleck and Noel Morris developed the first MAIL program. In the future, other scientists have made efforts to create a modern look and functionality of e-mail:
- Ray Tomlinson - special mail progammamy and the introduction of the @ symbol, which linked the username and the domain name in the address bar.
- Larry Roberts is a program for creating and sorting lists of letters.
- Steve Walker - the first mailing list
- John Vittal is a mail program that provides the ability to compose a response to a received message, send letters and sort correspondence.
A significant event was in 1976, when the English Queen Elizabeth II for the first time took advantage of e-mail capabilities.
In three decades, e-mail has acquiredgreat popularity. Today, it takes a leading position in relation to other ways of transmitting information on the Internet. The software allows you to connect to any point of the world from any computer, send not only a text message, but also other types of files. In the e-mail came such concepts as "emoticons", "spam" and "viruses".
