Short for electronic mail, the sending of messages over a computer system to one or more individual users via a system that saves the messages until the recipient is ready to read them. It's one of the major applications both for the Internet and for internal company networks. Most electronic mail systems allow you send short notes directly by typing them into a message creation box, or to import or attach longer messages or non-text files. On the Internet, e-mail features are now built into several Web browser programs, or you can use a specialized e-mail program such as Eudora. Most internal networks that are not built on Internet-like standards require you to use a proprietary e-mail program.
E-mail is only one form of computer messaging--the Internet and many networks also support "chat" systems, in which both users must be online, and newsgroups and bulletin boards, in which the message is meant for public display.
