A client program enables the user to interact with a server in order to access information and services on the server computer. Files that can be transferred are stored on special computers called FTP servers. To access these files, an FTP client program is used. This is an interface that allows the user to locate the file(s) to be transferred and initiate the transfer process. 1996 Network Solutions, Inc.

Compression decreases file size. This enables more files to be stored on the server and makes file transfer times shorter. In order to use a compressed file it needs to be decompressed using appropriate software. It is a good idea to have current virus checking software on the computer before files are downloaded to it. 1996 Network Solutions, Inc.
