Netscape is a package of applications based around a web browser. It also includes a mail client and webpage builder. Once upon a time it was the most popular web browser out there, but was defeated by Micro$oft's Internet Explorer. It isn't updated as often as it used to be, although a new version has recently been released.
The source code for Netscape was released several years ago, and the Mozilla organization has been offering an open-source version of Netscape ever since called
Mozilla. It is similar in appearance to Netscape, and in fact the tables have turned: Netscape now looks to Mozilla for updates to its software. So if you want to get away from Micro$oft's Internet Explorer, which actually has been declared unsafe by the US Government, Mozilla is a great choice. You won't actually get rid of Internet Explorer, however: you simply download and use Mozilla for almost all of your websurfing, and leave IE for Windows Updates only. That will help you avoid a lot of spyware and virus problems right off the bat. If you don't need the email client and webpage builder that Mozilla or Netscape offers, and just want a good web browser, the Mozilla organization makes a fine one: Mozilla Firebird.
