Computers identify each other with numbers
rather than words. Each domain name is therefore assigned a numeric
equivalent, called an IP (Internet Protocol) address, which might look
something like this: 207.153.51.10 DNS (the Domain Name System) is a set
of distributed databases containing these numeric equivalents and their
corresponding domain names. DNS has servers located all over the Internet which
perform the translation between names and numbers for other computers. This
arrangement allows users to invoke an easy-to-remember name (yourname.com)
rather than a difficult string of numbers when seeking out a site on the
Internet.
