The World Wide Web

• The World Wide Web (the Web or WWW) was created in 1989 at the European Particle Physics Laboratory in Geneva, Switzerland, as a method for incorporating footnotes, figures, and cross-references into online hypertext documents, using a protocol known as the hypertext transfer protocol (HTTP).
• A hypertext document is a specially encoded file that uses the hypertext markup language (HTML).
• This language allows a document�s author to embed hypertext links (also called hyperlinks or just links) in the document.
• HTTP and hypertext links are the foundations of the World Wide Web.
• Hypertext document; more commonly called a Web page; on a screen, you can click a word or picture encoded as a hypertext link and immediately jump to another location within the same document or to a different Web page.
• A collection of related Web pages is called a Web site.
• Web sites are housed on Web servers.
• The terms World Wide Web and Internet used interchangeably, as through they are the same.
• However, the Web is simply a type of service available to persons who can access the Internet�s resources.
