Communication Services

Electronic mail (e-mail) is the most important and popular communication service.
When one user wants to send a message to another Internet user, he/she types the message into
a special computer program, adds the e-mail address of the recipient, and sends the message
off through the network. Typically, the message reaches its destination almost immediately,
even when it is on another continent. Practically all gateways between the Internet and other
computer networks can handle e-mail messages.
The major advantage of e-mail over regular mail is that an e- mail message comes in electronic
form. Therefore, it can easily be handled and interpreted by a computer program.
