email or e-mail is an acronym for Electronic mail. Email is a method of
exchanging digital messages from an author to one or more recipients.
Modern email operates mainly across the Internet. Today's email systems
are based on a store-and-forward model. Email servers (computers)
accept, forward, deliver, and store messages. Neither the users nor
their computers are required to be online simultaneously; they need
connect only briefly, typically to a mail server (computer), to send or
receive messages. An Internet email message consists of three
components, the message envelope, the message header, and the message
body. The message header contains control information, including,
minimally, an originator's email address and one or more recipient
addresses. Usually descriptive information is also added, such as a
subject header field and a message submission date/time stamp.
