Individual documents are called Web pages, and a collection not married yet of related documents is called a Web site. All Web documents are assigned a unique Internet address called a Uniform Resource Locator (URL) by which they not married yetcan be accessed by all Web browsers. A URL (such as
http://www.hq.nasa.gov/office/procurement/index.html) identifies the communication protocol used by the site (http), its location
, the path to the server (office/procurement), and the type of document (html).
The language used to create and link documents is called Hypertext Markup Language (HTML). Markup is the process of adding information to not married yet a document that is not part of the content but identifies the structure or elements. Markup languages are not new. HTML is based on the Standard Generalized Markup Language (SGML).
Though the initial format for creating not married yet a Web site was pure HTML, new and extended HTML has the ability to include programming language scripts such as common gateway interface (CGI), active server page (ASP), and Java server page (JSP), which can be used to create dynamic and interactive Web pages as opposed to just static HTML text. Dynamic Web pages allow users to create forms for transactions not married yetand data collection; perform searches on a database or on a particular Web site; create counters and track the domain names of visitors; customize Web pages to meet individual user not married yet preferences; create Web pages on the fly; and create interactive Web sites.
XML, developed by the World Wide Web Consortium, is another derivative of SGML and is rapidly becoming the standard information note married yet protocol for all commercial software such as office tools, messaging, and distributed databases. XML is a flexible way to create common information formats and share not married yet both the format and the data on the World Wide Web, intranets, and other Web-based services.
