Brief History of Internet
| We are all so dependent on the Internet and cannot function without it. However, not many people know the history of the Internet. So, here is a brief history of the Internet to tell you more about how the WWW started. |
It all started in the early 1960s, when J.C.R. Licklider of MIT came up with this innovative idea of interconnected computers. In late 1962, he moved to the Defense Advanced Research Projects Agency (DARPA) to implement this idea. The theory of using packet switching for connections was developed by Leonard Kleinrock.
The first time two computers (computer in Massachusetts to computer in California) were connected using telephone lines was in 1965. Lawrence Roberts of MIT headed this task, but found the telephone lines to be inadequate.
When Kleinrock's packet switching theory was found to work, Roberts moved to DARPA to develop the ARPANET.
The ARPANET launched in 1969, and it was used only by professionals and experts. It was designed to provide communication abilities, even if computers sites were destroyed in a war attack. In 1974, Ethernet, the protocol for local networks, first came out. TCP/IP architecture developed the internet in the 70s. It replaced Network Control Protocol (NCP), and came into widespread use in 1983. The internet's backbone NSFNet came out in 1986. However, even at this time, the internet was not used for commercial purposes. This came about as email, telnet and FTP commands were developed.
Today, the internet is a widely used form of communications. With the introduction of the wireless internet, it has become now more prevalent than ever, and technology has made internet connectivity possible through various communication devices like PDAs, mobile phones, computers, laptops, and much more.
