<td>'''20'''</td><td>'''FTP'''<td>'''File Transfer Protocol (Data)''' - The File Transfer protocol provides a mechanism for transferring specific files between network connected computer systems(usually a Linux or UNIX based system). Transfer is typically performed using the ''ftp'' client which provides a range of commands used to connect to a remote server for the purpose of uploading or downloading files. Most modern web browsers also have the ability to browse and download files located on a remote FTP server. FTP uses TCP (rather than UDP) to transfer files so is considered to be a highly reliable tranport mechanism.</td>
