anguage) The standard document format for Web pages, defined by the Internet Engineering Task Force (IETF). Every Web page contains HTML tags (codes) embedded in the text that define the page layout, fonts and hypertext links. The link contains the URL (address) of another Web page on that same server or any server worldwide, hence "World Wide" Web. The HTML tags also define the graphic elements on the page, each of which is a separate file on a local or remote server. See hypertext
Since its inception by Tim Berners-Lee in the early 1990s, new versions of HTML have added features such as interactive forms, blinking text, custom backgrounds and tables of contents. To keep current, vendors have to update their Web browsers to accommodate the new tags; however, each new HTML version is backward compatible (mostly) with older versions.

World Wide Web Linking
Web pages are accessed by their Web address, which is known as a "uniform resource locator" (URL). A website's home page is an HTML document, which contains links to other HTML documents that can be stored on the same server or on a Web server anywhere in the world.
Web Server Fundamentals
Web browsers communicate with Web servers via the TCP/IP protocol. The browser sends HTTP requests to the server, which responds with HTML pages and possibly additional programs in the form of ActiveX controls or Java applets. See HTTP
