Addresses are necessary for virtually everything we do on the Internet. In TCP/IP the IP is a mechanism for providing addresses for computers on the Internet. Internet addresses have two following forms:

• Person understandable which is expressed as words
• Machine understandable which is expressed as numbers

The following may be a typical person understandable address on Internet:

VVS @ expertsmind .in

VVS is username which generally is the name of the Internet account. This name is same as the one, that you may use while logging into the computer on which you have your Internet account. Logging in is the procedure of gaining access to your account on a computer, which is shared through several users. Your Internet account is made on it.

.in is a domain top or what part in - It refers to "where" part which is a country code.
