The Internet 2: the World Wide Web

The connection of networks throughout the world forms the Internet which provides a range of different services, such as email, newsgroups, and file transfer. One of the newest and most popular services on the Internet is theWorld Wide Web which is commonly referred to asthe Web, or simply asWWW.

Aweb browser program provides a graphical user interface for the Internet allowing users to view linked documents calledWebPages. When a user clicks on aWebPages link, orhyperlink, the browser fetches and displays the linked webpage. Linked WebPages may be stored on different servers in different parts of the world. A set of hyperlinked WebPages stored on the same web server is known as awebsite. Websites are available for an enormous range of topics, including news, sports, entertainment, education, and sale of goods.

Because there are so many websites on the Web, it is often difficult to find the information you are looking for. Special websites have been set up that use programs calledsearch engines to search the Web for the information you need. Normally, you fill in a form on a search webpage to indicate what you are looking for and then click a search button to start the search engine. After searching the Web, it displays a webpage with hyperlinks to the websites that contain the information you are looking for. One of the most popular search engine websites is calledYahoo. When you find a webpage that you want to return to, you can store a hyperlink to the webpage in abookmark orfavorites area of the browser. (Note US spelling offavorites.) When you want to return to the webpage, you only need to click on the appropriate bookmark.

Each webpage has a unique web address sometimes known as auniform resource locator (URL). Web addresses often start withhttp:// www, and each part of the web address is separated by a dot (.) or a slash (/). Http stands forhypertext transfer protocol, which is the standard way of communicating on the World Wide Web. A typical browser program has the following components:
