www vs Internet
Summary: Difference Between www and Internet is that World Wide Web a widely used service on the Internet, consists of a worldwide collection of electronic documents. Each electronic document on the Web, called a Web page. While, The Internet, also called the Net, is a worldwide collection of networks that links millions of businesses, government agencies, educational institutions, and individuals.
The World Wide Web (WWW), or Web, a widely used service on the Internet, consists of a worldwide collection of electronic documents. Each electronic document on the Web, called a Web page, can contain text, graphics, animation, audio, and video. Additionally, Web pages usually have built-in connections to other documents. A Web site is a collection of related Web pages and associated items, such as documents and pictures, stored on a Web server.
A Web server is a computer that delivers requested Web pages to your computer. Some industry experts use the term Web 2.0 to refer to Web sites that provide a means for users to share personal information (such as social networking Web sites), allow users to modify Web site content (such as wikis, which are discussed later in this chapter), and have application software built into the site for visitors to use (such as e-mail and word processing programs).
One of the major reasons business, home, and other users purchase computers is for Internet access. The Internet, also called the Net, is a worldwide collection of networks that links millions of businesses, government agencies, educational institutions, and individuals. The Internet is a widely used research tool, providing society with access to global information and instant communications.
Today, more than one billion home and business users around the world access a variety of services on the Internet. The World Wide Web, or simply the Web, and e-mail are two of the more widely used Internet services. Other services include chat rooms, instant messaging, and VoIP (Voice over Internet Protocol).
The Internet has its roots in a networking project started by an agency of the U.S. Department of Defense. The goal was to build a network that (1) allowed scientists at different locations to share information and work together on military and scientific projects and (2) could function even if part of the network were disabled or destroyed by a disaster such as a nuclear attack. That network, called ARPANET, became functional in September 1969, linking scientific and academic researchers across the United States.
The original ARPANET consisted of four main computers, one each located at the University of California at Los Angeles, the University of California at Santa Barbara, the Stanford Research Institute, and the University of Utah. Each of these computers served as a host on the network. A host or server is any computer that provides services and connections to other computers on a network. By 1984, ARPANET had more than 1,000 individual computers linked as hosts. Today, more than 550 million hosts connect to this network, which is known now as the Internet.
The Internet consists of many local, regional, national, and international networks. Both public and private organizations own networks on the Internet. These networks, along with telephone companies, cable and satellite companies, and the government, all contribute toward the internal structure of the Internet.
Each organization on the Internet is responsible only for maintaining its own network. No single person, company, institution, or government agency controls or owns the Internet. The World Wide Web Consortium (W3C), however, oversees research and sets standards and guidelines for many areas of the Internet. More than 350 organizations from around the world are members of the W3C.
