File Transfer Protocol
File Transfer Protocol (FTP) is a standard network protocol used for transferring files between a client and a server on a computer network. It provides a simple and efficient way to upload, download, and manage files remotely.
FTP operates on the client-server model, where the client initiates a connection to the server using a designated port (usually port 21). Once connected, the client can authenticate itself and navigate through the server's file system using commands such as LIST, GET, and PUT.
FTP supports various transfer modes, including ASCII and binary, allowing for the transfer of different file types. It also provides features like resume functionality, allowing interrupted transfers to be resumed from the point of interruption.
While FTP is widely used, it has some security vulnerabilities, such as transmitting data in plain text. To address these concerns, secure alternatives like FTPS (FTP over SSL/TLS) and SFTP (SSH File Transfer Protocol) have been developed.
In conclusion, FTP is a reliable and efficient protocol for transferring files over a network. Its simplicity and widespread support make it a popular choice for various applications, although security-conscious users may prefer its secure alternatives.
