Use font size 12. What is a Browser? A browser is a computer program that resides on your computer enabling you to use the computer to view WWW documents and access the Internet taking advantage of text formatting, hypertext links, images, sounds, motion, blogs, and other features. Firefox and Internet Explorer are currently the leading "graphical browsers" in the world (meaning they facilitate the viewing of graphics such as images and video and more). There are other browsers (e.g., Mozilla, Safari, Opera). Most offer many of the same features and can be successfully used to retrieve documents and activate many kinds of programs. Browsers all rely on "plug-ins" to handle the fancier files you find on the Web. Plug-ins is sub-programs stored within a browser or elsewhere in your computer especially to support special types of files you may click on. If you click on a link, and your computer does not currently have the plug-in needed for the file you clicked on, you are usually prompted with an opportunity to get the plug-in. Most plug-ins is free and easy and safe to install on your computer; follow the instructions you are given. The main way in which browsers differ is in the convenience features they offer for navigating and managing the Web and all the URLs you may want to keep track of. Netscape and Internet Explorer both offer the ability to documents, download them to diskette, print them, and keep track of where you've been and sites you want to "bookmark" or "Add to Favourites" (Microsoft's name bookmarks). a) Save the document as browser.
