a.Basics of electronic mail

What is an electronic mail ?

Electronic mail, most commonly referred to as email or e-mail since ca. 1993,[2] is a method of exchanging digital messages from an author to one or more recipients. Modern email operates across the Internet or other computer networks. Some early email systems required that the author and the recipient both be online at the same time, in common with instant messaging. Today's email systems are based on a store-and-forward model. Email servers 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, for as long as it takes to send or receive messages.

Email Addressing

A name that identifies an electronic post office box on a network where e-mail can be sent. Different types of networks have different formats for e-mail addresses. On the Internet, all e-mail addresses have the form:

@<domain name >



Mailbox – Inbox and Outbox

An area in memory or on a storage device where e-mail is placed. In e-mail systems, each user has a private mailbox. When the user receives e-mail, the mail system automatically puts it in the mailbox.

The mail system allows you to scan mail that is in your mailbox, copy it to a file, delete it, print it, or forward it to another user. If you want to save mail, it is a good idea to copy it to a file, because files tend to be more stable than mailboxes.
