Domain Names
Every computer that hosts data on the Internet has a
unique numerical address. For example, the numerical
address for the White House is 198.137.240.100. But
since few people want to remember long strings of
numbers, the Domain Name System (DNS) was
invented. DNS, a critical part of the Internet's technical
infrastructure, correlates a numerical address to aword.
To access the White House website, you could type its
number into the address box of your web browser. But
most people prefer to use "www.whitehouse.gov." In
this case, the domain name is whitehouse.gov.
