A. Compression is the technique of bundling a file into a format which is smaller than its' original size. Using complex mathematical algorithms, files are compressed into smaller packages for the purpose of transfer. With compression, a file that would otherwise take a very long time to download can be downloaded in a fraction of that time.

Q. What are some other reasons compression would be used?

A. Many times a file that is very large will be broken down into smaller chunks so that when downloaded it can easily be transferred to floppy disk. Compression can also make the transfer of data over the internet more reliable than transferring uncompressed files.

Q. Is there more than one type of compression?

A. Yes, there are many different varieties of compression. One version that you may already be familiar with is the graphical compression named .gif. Many of the image files that you view on the internet are compressed as .gif's. Your browser then decodes the .gif's so that you can view them. Other types of compression are .arj, .hqx, .rar, and .zip. These are the most commonly used file compression types on the internet.

Q. Once I have downloaded a compressed file how do I uncompress it?

A. In order to uncompress a file you must have a utility that is capable of decompressing the desired file type.

Q. Where can I download the utilities that will allow me to uncompress a file?

A. Below you will find links to download many of the most popular file decompression utilities. If there is a type that you don't see here, search for it using a search engine.

A. The Usenet Compression FAQ is a very good resource.
