WWW

The World Wide Web (abbreviated as WWW, commonly known as the Web) is a system of interlinked hypertext documents (Web sites) accessed via the Internet.

The Web is a subset of the Internet.  The Web consists of pages that can be accessed using a Web browser.  The Internet is the actual network of networks where all the information resides.

The Hyper-Text Transfer Protocol (HTTP) is the method used to transfer Web pages to your computer.  With hypertext, a word or phrase can contain a link to another Web site.  All Web pages are written in the hyper-text markup language (HTML), which works in conjunction with HTTP.

The World Wide Web is the most widely used part of the Internet.  Its outstanding feature is hypertext, a method of instant cross-referencing.  In most Web sites, certain words or phrases appear in text of a different color than the rest; often this text is also underlined.  When you select one of these words or phrases, you will be transferred to the site or page that is relevant to this word or phrase.  Sometimes there are buttons, images, or portions of images that are "clickable."  If you move the pointer over a spot on a Web site and the pointer changes into a hand, this indicates that you can click and be transferred to another site.

Using the Web, you have access to millions of pages of information. Web browsing is done with a Web browser such as Internet Explorer, Firefox, Chrome or Safari.  With a Web browser, one can view Web pages that may contain text, images, videos, and other multimedia and navigate between them via hyperlinks.
