In early 1998, Netscape announced that it would release the source code of its next-generation browser as a part of its open source strategy. The source code contains the programming elements that make up the Communicator software application. It is not a compiled program and thus cannot be used by traditional software end-users. Mozilla, as it is called, was released as C++ source code and caused a flutter of excitement in part because of its implementation of the World Wide Web Consortium’s standards, eXtensible markup language (XML), and the resource description framework.

Browsers are software programs that render web pages and help you move through the web.
The browser that triggered the World Wide Web explosion was Mosaic, a public domain graphical user interface (GUI) from the National Center for Supercomputer Applications (NCSA). Released in 1993, Mosaic made it possible to design documents containing images for display over the internet. Up to that point, an internet document was basically just a bunch of text on a server. In 1994, Mosaic ship-jumper Marc Andreessen released Netscape 1.1, following Mosaic’s successful lead, by distributing the browser free of charge on the internet in order to establish a wide user base.
Popular web browsers today include Internet Explorer, Firefox, Safari and Opera. See Browser Charts for information on some of their differences.
Caching (pronounced CASH-ing) is a technique computers use to save memory by storing frequently accessed files.
Web browsers have caches that keep recently downloaded web pages handy. Browser caches are typically kept on your local drive, and you can usually adjust the amount of memory or disk space allotted for the cache. The benefit of web caches is that you can access a cached page much more quickly than if you downloaded it from a distant server.
A filter is a program that receives a specified kind of data, then manipulates and outputs the results.
Your word processor’s find and replace function is a good example of a filter.
Flatten is a function in image-processing programs, such as Adobe Photoshop, to combine multiple layers into one file.
For example, in order to move the file to another program or save it as a GIF or JPEG, you will have to use the flatten function to combine all layers into one.
