FTP (File Transfer Protocol)

Overview

File Transfer Protocol (FTP) is a standard network protocol used for transferring files between a client and server on a computer network. Developed in 1971, FTP is built on a client-server model architecture and uses separate control and data connections between the client and server, making it one of the oldest protocols still in use for file transfer operations.
