E-mail

E-mail stands for Electronic Mail.  This is the internet's improved post office.

With E-mail you write a letter on the computer and send it to another person's Internet address, much like you would when mailing a letter, except it does not require a stamp.  Actually, it costs you nothing.  

In most cases, the message gets anywhere in the world in less than one minute. You cannot send a package like you would with a shipping company, but you can attach a file.  

The addressee will get this 'letter' the next time he or she checks for new E-mail on his or her computer.
