How does FTP work?

FTP uses TCP/IP protocols to upload or download files to our computers from other sources. The source can be a web server or a remote host over the Internet. FTP transfer involves two computers —

1. FTP Server — The FTP server is a computer that has an FTP address just like an http website. It is an important component in FTP architecture that initiates a client's request for an FTP connection from other computers and helps in transferring data back to client over the Internet.
2. FTP Client — The FTP client works on client/server architecture. An FTP client initiates a request to the FTP server for connection using the FTP protocol. Once the connection is established, client software can be used to download, upload, and manage files and folders on a server.
