The File Transfer Protocol (FTP) is a protocol used widely for the efficient transfer of data files from a source computer to an end user on a personal computer network. FTP stands for, “file transfer protocol”. FTP servers are designed to act as connection points for computers that are either connected to the internet or are capable of receiving and sending messages through this protocol. FTP transfers file contents from one computer to another either temporarily or permanently. Temporary files are transferred over this method on a regular basis while permanent files are transferred only when the user is ready to save the data permanently. FTP also acts as a protocol for controlling the access to computer resources such as printers, modems, FTP clients, and FTP servers.
File transfer protocol is usually used to exchange text and multimedia content such as images, music, video and application software. A very popular example of File Transfer Protocol is the Internet, which has many common applications including chat rooms, file sharing, e-mailing, news bulletin board, fax services, online games and many more. FTP provides security features to ensure secure data transfer for both the user and other users of the system. Security features include checksum verification, encryption, and MAC (Message Authentication Code), which ensure integrity of the transmitted data. File transfer protocol also includes different methods for transferring files such as ftp over connection, rar over connection, binary over connection, and email over connection.
Some of the common file transfer protocol (FTP) applications include telnet, HTTP, FTP over LPN, and ISAPI over HTTP. Telnet is the most commonly used application of FTP. FTP over LPN is similar to telnet, but it is more secure as it overcomes some of the disadvantages of the latter such as lack of portability, possible security breaches, and unable to monitor activity on the server side. The FTP over HTTP protocol allows users to connect to a remote host through the internet while allowing FTP access to the local host. In general, an FTP service allows the user to transfer files between computers by providing a browser-based interface for multiple users at the same time. FTP allows the user to work in different stages concurrently and makes it easier to coordinate various tasks simultaneously.
