This definition is also listed under presence, Web site and Website.
A Web site is a collection of Web files on a particular subject that includes a beginning file called a home page. For example, most companies, organizations, or individuals that have Web sites have a single address that they give you. This is their home page address. From the home page, you can get to all the other pages on their site. For example, the Web site for IBM has the home page address of http://www.ibm.com. (In this case, the actual file name of the home page file doesn't have to be included because IBM has named this file index.html and told the server that this address really means http://www.ibm.com/index.html.)
Since it sounds like geography is involved, a Web site is rather easily confused with a Web server. A server is a computer that holds the files for one or more sites. A very large Web site may reside on a number of servers that may be in different geographic locations. IBM is a good example; its Web site consists of thousands of files spread out over many servers in world-wide locations.
A synonym and less frequently used term for Web site is "Web presence." That term seems to better express the idea that a site is not tied to specific geographic location, but is "somewhere in cyberspace." However, "Web site" seems to be used much more frequently.
