There are many different web browsers (programs for looking at web pages). Some names of web browsers are: Lynx (a text only browser), Firefox, Mozilla and Internet Explorer (both graphical browsers). The browser which you will be using in the labs will be either Mozilla or Firefox. You will probably want to run Mozilla in the background (by typing mozilla & in an xterm) or Mozilla-Firefox by typing firefox &.
Microsoft's Internet Explorer is not available for the UNIX operating system so we will not be discussing it here. It behaves in a similar way to Mozilla-Firefox and Mozilla.
There are quota limits associated with web usage. See section 1.9.6 on page for further details.
