The Domain Name System (DNS)
helps users to find their way around the Internet.
Every
computer on the Internet has a unique address – just like a
telephone number – which is a rather complicated string of
numbers.
It is called its "IP address" (IP stands for
"Internet Protocol").
But it is hard to remember
everyone's IP address.
The DNS makes it easier by allowing a
familiar string of letters (the "domain name") to be used
instead of the arcane IP address.
So
instead of typing 207.44.172.47, you can type
talou.net.
It is a "mnemonic" device that makes addresses easier to
remember.
