FTP is the short term used for File Transfer Protocol. As what the name implies, it is used to transfer or copy files between computers over a network. A protocol in information technology, on the other hand, is the special set of rules that is used by the end points in a telecommunication network when they communicate. Protocols indicate connections among the communicating entities.
Similar to HTTP or the Hypertext Transfer Protocol which transfers web pages that can be displayed in web browsers and associated files, and the SMTP or the Simple Mail Transfer Protocol which transfers email messages, an FTP is an application protocol that utilizes the TCP/IP protocols of the internet. The usual application of an FTP is to transfer web page files from its author to the computer that serves as the server.
Aside from that, it is also used to download files and other programs from other servers into your computer.
