So what exactly is a browser?
It is a software application that allows you to look at (or browse) the World Wide Web. Just like Word Perfect, Word, and Macwrite are all word processing applications, Netscape, Mosaic and Lynx are all WWW browsing applications. Hence they are known as browsers. So when you read, "Use your browser's Back button", it mean use the "Back" button that comes with your software application (aka browser) that you use to look at the Web.
If you are using Netscape to look at the Web, your browser is Netscape. In Netscape, the browser's "Back" button is the leftmost button on the toolbar at the top of the screen. It is grey, has an arrow pointing backwards on it, and it probably has the word "Back" on it. Find it now. So when the program says, "Use your browser's "Back" button.", it wants you to use this button.In Mosaic:
If you are using Mosaic to look at the WWW, then Mosaic is your browser. Mosaic's "Back" Button has a triangular shape pointing to the left on it and has no words. It is in the middle of the toolbar near the top of the screen beneath the words Navigate and Buttons. Find it now if you are using Mosaic.Please Note: If your browser is neither Netscape nor Mosaic, there is information available on how to download the newest version of Netscape.
