E-mail

E-mail

Electronic mail, called e-mail was started in the late 1960’s by the armed forces of the United States of America. The army or military officers were looking for a way that communications should be carried out in the event of a large-scale nuclear war. They needed a system that would be very decentralized, reliable, and fast in case central instructions were destroyed. They came up with email.

In the early 1970’s, e-mail was  limited to the United States military, defense contractors and universities doing defense research. By the 1970’s it had begun to spread more broadly within university communities. By the 1980’s, academics in a number of university disciplines were using e-mail for professional collaboration. The early 1990’s saw an explosion of the use of e-mail and othere computer networking tools for a wide range of professional, academic, and personal purposes. Whereas a few thousand people using e-mail in 1980, it was estimated that in 2000, more than 25 million people throughout the world were using it.

E-mail is a way of sending message from one computer to one  or more computers around the world. First, you write down the e-mail address of the person you are sending the message to. Then you compose the message, either by writing it directly in a special e-mail software programme or by writing it first in the word processing programme, then transferring it into the e-mail software. You push a button to issue a simple command to send the message. The computer system you’re connected to will break the message up into tiny pieces and send them electronically to the destination, usually over common telephone lines. The pieces might travel through different routes to various computers on the way. Then , the computer will re-assemble them into a message that can be read. The person receiving the message can then log into his or her computer account at a convenient time and read the mail.

Today, in Sri Lanka, many professionals, especially those in urban areas, use E-mail. It’s very useful and cheaper than making telephone calls. While overseas telephone calls are very expensive, e-mail messages can be sent to the same people at a fraction of the cost. Of course, both parties must have access to computers and telephones. The main problem with e-mail is that it’s so depended on telephone lines and electricity, that in developing countries like ours, it’s not totally reliable because you never know when the telephones will be out of order, or when there’ll be a power cut. But as far as personal messages are concerned, e-mail is quicker and cheaper than other methods such as the telephone or “snail mail”

History of Email 

Email is the direct translation of the interoffice, inter-organizational paper based mail system. In 1978, the first email system was created at UMDNJ in Newark, NJ. Several technological components were critical to the invitation of email. Following this invention, various other products starting in 1984, came into the commercial market as shown in the info graphic below. After the Smithsonian’s acceptance of the papers and artifacts documenting the invention of Email, on February 16,2012, industry insiders unleashed and irrational denial of the invention and initiated personal attacks aimed to discredit Dr. Ayyaduraj and his life’s work. These attacks were like an immune response reacting to a potential invader, in this case, ayyaduraj being seen as an invader by a vocal minority of industry insiders who believe they can monopolize innovation.

@ Symbol

Ray Tomlinson chose the @ symbol to tell which user was "at" what computer. The @ goes in-between the user's login name and the name of his/her host computer.

First Email

The first email was sent between two computers that were actually sitting besides each other. However, the ARPANET network was used as the connection between the two. The first email message was "QWERTYUIOP".

Ray Tomlinson is quoted as saying he invented email, “Mostly because it seemed like a neat idea." No one was asking for email.
