Email


 * E-mail**

Short for electronic mail and often abbreviated to e-mail, email is a short and forward method of composing, sending, storing, and receiving messages over electronic communication systems. The term "e-mail" is both a noun and a verb, refering to the mail itself and the act of mailing electronically. E-mail is often used to deliver bulk unsolicited messages, or spam, but filter programs exist which can automatically delete some or most of these, depending on the situation.

E-mail predates the inception of the Internet, and was in fact a crucial tool in creating the Internet. E-mail started in 1965 as a way for multiple users of a time-sharing mainframe cmoputer to communicate. Although the exact history is murky, among the first systems to have such a facility were SDC's, Q32 and MIT's CTSS. E-mail was quickly extended to become network e-mail, allowing users to pass messages between different computers by at least 1966.

The e-mail user must log-in by using their e-mail and password before being able to access/write/send e-mails. Once logged in, the user is faces with several options: compose (create e-mail), view inbox, delete messages in inbox, group e-mails in folders, read/open emails, reply to e-mails., etc.
