FTP (File Transfer Protocol)
Overview
FTP is a standard network protocol used for the transfer of computer files between a client and server on a computer network. It is built on a Client-Server Model architecture and uses separate control and data connections between the client and the server.
Key Features of FTP
- Data and Control Channels: FTP uses two channels, a command (control) channel for controlling the conversation and a data channel for transmitting file content.
- Anonymous Access: Often allows users to access files with a generic username and without a password.
- Active and Passive Modes: Supports active and passive modes for establishing data connections.
Usage
FTP is widely used for exchanging and manipulating files over any network that supports the TCP/IP protocol. It has applications in website management, corporate data transfer, and backup systems.
