FTP is fully named as File Transfer Protocol. With the help of FTP one can remotely transfer their data to the server or to precisely say to another computer. This a standard protocol to transfer or sharing files across the World Wide Web.

With the help of FTP one can exchange files between computers on the Internet just like HTTP (Hyper Text transfer protocol) that transfers WebPages and related files or SMTP (Simple mail transfer protocol) that transfers emails. FTP uses the Internet’s TCP/IP protocols. FTP is most commonly used to download a file from a server using the Internet or to upload a file to a server (e.g., uploading a Web page file to a server).
