The WWW is made up of documents that are called pages but which contain a rich array of static and changing images, text and even sound. Each page is connected or hyperlinked to other pages. The images one sees and which contain the hyperlinks are the result of course, of computer programming and script writing. It is this language which allows the user to move, surf or browse from page to page. A browser provides the interface between the unintelligible computer language and the image or text that the Internet user reads.
Sophisticated browsers allow the user to view a full picture.
Browsing or linking from one highlighted point to another can take one to locations around the world. It is similar to an address on an envelope which tells the post office where to deliver it. The URL tells the computer where a particular site is located and where the information can be found. The second element in the URL which follows the two forward slashes is often composed of three names and identifies the location of the site of the computer which contains the information. The final element is the particular file holding the information.
