Electronic mail is the use of a network to transmit text messages, memos, and reports.
Users can send a message to one or more individual users, to a predefined group, or to all users on the system. When you receive a message, you can read, print, forward, answer, or delete it. Not only are there different applications used to send and receive email such as MS Mail, VAX Mail, Eudora, Pine mail etc. EMail is very fast. A message you send from one side of the world can arrive at the other side in a matter of minutes under the right conditions.
