FTP is a standard protocol that uses the Internet TCP/IP protocol to transfer files from on computer to another. FTP is most commonly used to upload and download files which are then available to be viewed by multiple computers with a vast range of operating capacities. Connecting to an FTP server often can be rather difficult and is normally the most tedious step in the file transfer process. Once a connection has been established servers send/ receive various codes to/from FTP clients. FTP clients are the programs that initiate and maintain a connection to an FTP server. Some codes relayed between FTP clients and servers will represent errors, but most of the FTP clients and servers simply communicate the status of the connection. FTP clients are vital in ensuring that FTP sites run smoothly.
