Electronic mail (E-mail)-

E-mail stands for Electronic mail. It is the most widely used tool to send messages electronically i.e. through computers on a network.

E-Mail Address-

 

Each user of email is assigned a unique name for his email account. This name is known as E-mail address. Different users can send and receive messages according to the e-mail address.

 

E-mail is generally of the form username@domainname. For example, sachin@mnclasses.com is an e-mail address where sachin is username and mnclasses.com is domain name. The username and the domain name are separated by @ (at) symbol. Spaces are not allowed in e-mail address.
