E mail (1971)

TOMLINSON DEVELOPS A PROGRAM ALLOWING COMMUNICATION BETWEEN COMPUTER NETWORK.

Messages that distributed by electronic means from one computer to one or more computer via network. more plainly email is a message that may contain text, images, or other attachment sent through a network to a specified individual or group of individual is called e mail.

In 1969 a company called bolt Barenek and Newman won the contract to develop a communication network called ARPANET that would enable scientists and researchers to use each others computer facilities. During it's development, an engineer named Ray Tomlinson started to experiment with the coding of two program. SNDMSG allowed members of same network to exchange message among one another, whereas CPYNET allowed file transfer to occur between two separate network. It occurred to Tomlinson that by combining the two he could create a system that would make message transfer possible between different user of independent network.

One of most significant decision by Tomlinson was his choice of the symbol to separates the users name from the host network name. It was a fairly logical choice, but one that revived the rather esoteric symbol and saved it from the brink of linguistic extinction.

Unaware of the global significance that the 200 lines of code that made up the email program would have, tomlinson neglected to note what he wrote in the first ever sent (he claims it was something banal like "QWERTYUIOP" or "TESTING  1 2 3 4").

Allegedly, when Tomlinson first demonstrated his program to coworker , latter told him not to show the system to anyone because it was not part of their job description . Tomlinson has since said that even though there was no direct stated objective to create email, the ARPANET project was in fact a giant and worthwhile investigation into the multifarious uses of computer communication

some people use internet based application and some use program on their computer to access and store the email
