Here comes the role of FTP client software. Mostly, it is seen that maximum servers have a basic FTP function that works through any browser as a whole but it is quite difficult to use. It is used when you have to upload a file from your computer (client) to the remote server over a network. You can send and receive files from a server using this protocol. FTP is the protocol (file transfer protocol) which helps you connect to your remote server and transmit the files.
