E-mail address

Sending and receiving e-mails requires an e-mail address in any of the website that provides e-mail service.

An e-mail address is divided into two parts, namely, the username and the  name of the mail server. The two parts are separated by the symbol @. The structure of an e-mail  address is :

                  username@mailservername.com

For example : student05@yahoo.com is an e-mail address where,

                        student05 = the username

                        yahoo = the name of the e-mail server

                        .com = a commercial website
