File Compression
File compression is a way of reducing the size of one or more files, so that they don't take up a lot of space on a server or hard drive and can travel faster over a network. File compression is accomplished with software that uses mathematical equations (algorithms) to condense repeated data into smaller codes. You need another separate software program to decompress (expand) the data, and restore it to its original form.
