A domain name is a unique name that identifies an Internet site. The Internet is made
up of millions of computers and networks, all with their own domain name or unique address.
When the Internet was young all the nerds got together and decided that every computer
on the Internet had to have an address. Of course that makes sense, doesn't it? How else
could we find each other? The decision was to give every computer an IP number
(Internet Protocol Number). This number consists of 4 parts separated by dots such
as 123.45.67.89 or 12.345.678.910.
But as the Internet grew it became obvious to some that there must be an easier way
to find someone than trying to remember a 10 or 12 digit number.
Ah... Domain Names were born!
And the DNS was born! (Domain Name System) If everyone got together they could give
names to each computer instead of a number. But someone has to keep track of what
name goes with what IP number. The DNS keeps track of domain names. Everyone still
has an IP number but the DNS automatically goes to that number when someone looks
for your domain name.
So now we can get a domain name of our choice and not have to worry about any number.
That is taken care of by the DNS.
Domain names have an extension such as .com, .net or .org. There are also other extensions
available such as .info, .biz, .us, etc.
