The correct answer is A. FTP.
FTP stands for File Transfer Protocol. It is a standard network protocol used to transfer files from one computer to another over a TCP/IP network, such as the Internet. FTP is a client-server protocol, which means that there are two programs involved in the transfer: a client and a server. The client initiates the transfer and the server responds
to the client’s requests.FTP is a very simple protocol. It uses two ports: port 21 for control data and port 20 for data transfer. The control connection is used to establish the connection between the client and the server and to send commands. The data connection is used to transfer the files.
FTP is a very versatile protocol. It can be used to transfer any type of file, including text files, images, programs, and even entire operating systems. It is also very secure. All data is transferred encrypted using the Secure Sockets Layer (SSL) protocol.
