Electronic Mail (E-Mail)

A method by which computer users can exchange messages with each other over a network. E-mail is probably the most widely used communications tool on the Internet. There are many quirky conventions to e-mail but most entail a To:, From: and Subject: line. One of e-mails advantages is its ability to be forwarded and replied to easily.

E-Mail Address

Your e-mail address is made up of several parts. By convention, addresses use lowercase letters with no spaces. The first part of the address, the username, identifies a unique user on a server. The @ (pronounced 'at') separates the username from the host name. The host name uniquely identifies the server computer and is the last part of the Internet e-mail address (E.G. username@hostname.com). Large servers, such as those used at universities or large companies sometimes contain multiple parts, called subdomains. Subdomains and the host name are separated by a period '.' (pronounced dot). The suffix at the end of the host name identifies the kind of organization operating the server. The most common suffixes are .com (commercial), .edu (educational), .gov (government), .mil (military) and .org (non-commercial). Addresses outside of the US sometimes use a two-letter suffix that identifies the country in which the server is located. Some examples include, .uk (United Kingdom), .ca (Canada), .jp (Japan)
