Collection of files and related resources accessible through the domain name .
Typical files found at a Web site are HTML documents with their associated graphic image files ( GIF , JPEG , etc.), scripted programs (in Perl , CGI , Java , etc.), and similar resources. The site's files are usually accessed through hypertext or hyperlinks embedded in other files. A Web site may consist of a single HTML file, or it may comprise hundreds or thousands of related files. A Web site's usual starting point or opening page, called a home page, usually functions as a table of contents or index, with links to other sections of the site. Web sites are hosted on one or more Web servers , which transfer files to client computers or other servers that request them using the {{link=HTTP">HTTP protocol. Although the term "site" implies a single physical location, the files and resources of a Web site may actually be spread among several servers in different geographic locations. The particular file desired by a client is specified by a URL that is either typed into a browser or accessed by selecting a hyperlink.
