People use the word address in 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. 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). 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.) 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.)
