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 the World Wide Web which is commonly referred to as the Web, or simply as WWW.
A web browser program provides a graphical user interface for the Internet allowing users to view linked documents called WebPages. When a user clicks on a WebPages link, or hyperlink, 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 a website. 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 called search 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 called Yahoo. When you find a webpage that you want to return to, you can store a hyperlink to the webpage in a bookmark or favorites area of the browser. (Note US spelling of favorites.) 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 a uniform resource locator (URL). Web addresses often start with http:// www, and each part of the web address is separated by a dot (.) or a slash (/). Http stands for hypertext transfer protocol, which is the standard way of communicating on the World Wide Web. A typical browser program has the following components:
| Component | Function |
| title bar | display the title of the current webpage |
| menu bar | provides access to drop-down menus of program features |
| toolbar | provides button icons for using the most common browser features |
| status bar | gives information about the current status of the program |
| address box | displays the current webpage address |
A typical browser toolbar has a variety of buttons including the following:
| Button Icon | Function |
| back | displays the previous visited webpage |
| forward | displays the next visited webpage |
| refresh | refreshes the current webpage display |
| home | goes to the first page set on the browser |
| search | goes to a web search engine |
