People use this word several ways. You can ask someone for the address of their server, or for their home page on the Web, or where to send e-mail. So an "address" can mean the unique location of either (1) an Internet server, (2) a specific file (for example, a Web page), or (3) an e-mail user. It is also used to specify the location of data within computer storage.

1) An Internet address or IP address is a unique computer (host) location on the Internet (expressed either as a unique string of numbers or as its associated domain name).

Example of an IP address expressed in dot notation:
Example of the domain name version:

For more information, see IP address.

2) A file (or home page) address is expressed as the defining directory path to the file on a particular server. (A Web page address is also called a Uniform Resource Locator, or URL.)


3) An e-mail address is the location of an e-mail user (expressed by the user's e-mail name followed by an "at" sign followed by the user's server domain name.)

Example: [email protected]

4) In a computer, a storage address is the beginning location of a sequence of data that is stored on some electronic storage medium.
