The term 'domain' has several different uses. The most common uses in computer networking are the following:
- Windows NT/2000/XP domain - a logical group of computers with centralised security and administration.
- Internet domain - a domain name (e.g. www.microsoft.com) is a way of identifying computers and resources on the Internet. Each domain name corresponds to a numeric IP (Internet Protocol) address (e.g. 188.8.131.52). The Domain Name System matches the domain name to the IP address and the Internet uses the IP address to send and receive data.
