One important use of Internet is communication between computer users by e-mail. E-mail allows users to send and receive messages, text, or other information through Internet. E-mail is further like a mailbox: the user can send messages no matter whether the receiver is on the network or not. When a message arrives, it is stored in the e-mail address. If there is an e-mail, a signal will indicate that a message is waiting to be read. Today e-mail has replaced the telephone for many messages. The user can read his message when it is convenient for him. He can read his message on the computer screen or print it out.
