HYPERLINK

          This is a connection between an element in a hypertext document, such as a word, phrase, symbol, or image. The user activates the link by clicking on the linked element, which is usually underlined or in a color different from the rest of the document to indicate that the element is linked. With hyperlinks, one can easily move through a cast amount of information by jumping from one Web page to another.

      By clicking the Autos command, it will jump to another page which shows the content of Autos. Hyperlink work in this way as it shows connection from home page to sub page.

THE WEB BROWSER

THE WEB BROWSER

          A web browser is a software program that enables one to access and view the Web pages. Web browser software is built on the concept of hyperlinks. This is used in jumping from one link to another in whatever order it chooses.       

          The three most popular browsers currently available are Microsoft Internet Explorer, Mozilla Firefox and Netscape Navigator. Most computers allow you to connect easily using either browser but for our discussion here, we will be using the Internet Explorer. There are various ways to open the Internet Explorer. Two of these are:

1.   Double-click the Internet Explorer icon on your desktop.

2.   Open the Start menu and select Internet Explorer from your list of programs.

                                                                                                  

Most web browsers are also capable of downloading and transferring files, providing access to newsgroups, displaying graphics embedded in the document and playing audio and video files associated with the document.

History of Browser

          On January 1993, the first browsers, Viola and Midas, were released for the X-Window system (Unix). At the same time, a Macintosh browser was released as an Alpha – version.

          On February 1993, the first popular graphical World Wide Web browser was NCSA Mosaic. It was released for all common platforms (Unix, Windows and Macintosh) on September 1993.

          When Marc Andreessen, the mastermind of Mosaic founded the Netscape and released a browser (the Netscape Navigator 1.0), he controlled 70% of the browser market. Microsoft saw this huge success and soon released a browser, the MS Internet Explorer, for free.

          Now, the new versions of both the browsers support most of the HTML elements. At present, the more widely used Web browsers for personal computers are the Microsoft Internet Explorer and the Netscape Navigator. Sometimes, while browsing the Web, when a site says “best viewed by Netscape Navigator” or “best viewed by Internet Explorer”, it means that the pages were programmed for that particular browser.
