The main difference between FTP and Telnet is that FTP is used when transferring files from one computer to another, while Telnet allows users to remotely log in to another computer, and once logged in, users can issue commands remotely. Both FTP (file transfer protocol) and Telnet are protocols that enable computers to communicate with each other.
Some of the other differences are listed below.
- It is possible to use FTP with a dedicated application, a command line and a majority of web browsers, while Telnet is confined to a command line.
- There are secure ways to utilize FTP (SSH File Transfer protocol), but Telnet will always be unsecure.
- FTP is widely used to upload files to Web servers; however, Telnet is mostly used to diagnose network services.
- FTP systems are usually encoded and transmit data in binary sets, thus enabling faster data transfer. In Telnet, the communication is non-coded.
Aside from the fact that they are both communication protocols, Telnet and FTP are both two-way systems. FTP can be used to upload files from clients to servers and also to transfer files from servers to clients. Telnet can be used to transfer files between two computers.
Open-source FTP applications like FileZilla are used to upload web files to web servers.
