E-mail is a very simple device that anyone can use. You create your E-mail, log on to your ISP (Internet Service Provider) and send your mail. Your message travels thru your ISP's mail server and routes it to the recipients mail server and then is placed in the recipients mail box. The message will sit in the recipients mail box until the person accesses the mail. This whole communications process is done using TCP/IP (Transmission Control Protocol/Internet Protocol).
The E-mail address is broken down as follows:
YourName@ Domain.Com The first part, "YourName" can be any predetermined name that you have chosen with your ISP. The "@" or (AT) symbol provides a break between "YourName" and the "Domain" name. It shows that you are at a certain domain. The ".Com" is the type of institution. It can also be .Org, .Net, .Edu...etc.
