Domain Name System is how the
Internet links together the thousands of
Networks that it is comprised of. The
DNS is utilized whenever you send an Email or access a particular
Web Page. Each computer on the Internet has a one of more Domain Names such as "fredbloggs.co.uk". The .co indicates a commercial organisation & the .uk indicates that the computer is in the United Kingdom. Standard conventions used in Domain Names include: ac - Educational institution; co - Commercial organization; com - Commercial organization; edu - Educational institution; gov - Non military government organizations; int - International Organizations; mil - Military government organizations; net - Networks; org - non profit organization. You will also see these codes in
URL's such as "homepages.enterprise.net/jenko/Glossary/G.htm". These DNS converts the Domain Names to a unique number known as an
IP address (the IP stands for
Internet Protocol). You will often see the IP address displayed by your Web
Browser when you are connecting to a particular computer.
