Domain names

Because a numerical IP address can be hard to remember, you can use the Domain Name Service (DNS) to identify a computer. A domain name is converted into an IP address by the DNS protocol.

A top level domain is two or three characters long and appears right of the domain name. For example, the "com" in the domain name corel.com, is a top level domain and stands for a commercial organization. The domain name corel.com replaces an IP address.
