Browsers: Browsers are programs that reside on a personal computer.  They download, bring a file or files from a distant computer to your local computer and display the text,  pictures, movies, etc. on your computer.  There are lots of different browsers with each having unique capabilities. Helper programs can be added to browser to perform diffirent functions The most common browsers are:

LYNX: this is a very primitive browser by current standards. It was designed for slow modem speed and only for text display and linking. LYNX will not display pictures, movies or sounds.

MOSAIC, NETSCAPE, EXPLORER: these browsers are all derivations of the MOSAIC browser developed at the University of Illinois. With the proper Helper files connected  these browsers can download and display pictures, movies, sounds and virtual reality files.  The newest versions allow an ever increasing variation in formatting of displays.

Helpers/Plugins: These are files that are accessed by the browser to perform special functions  such as play sounds or quicktime movies.   You add these helpers to your browser files to inable these tasks.
