FTP is an abbreviation for File Transfer Protocol - a way of copying information from one computer to another.
Information means archives of useful text, images, sounds, video clips, or software.
Find information, and copy it to your computer. When a new version of a software product is released, some authors make it available via FTP so that anyone can get a copy without having to wait for disks to be sent through the post. This is especially true of shareware and other 'public' software, which has looser or more creative copyright restrictions than commercial products. The distribution of shareware is one of FTP's most important applications. FTP extends the filing system inside your computer to include the whole Internet.
