FTP stands for File Transfer Protocol, which relies on client/server technology. It is a software application that transfers files between systems. The FTP protocol was developed in the 1970s and is one of the most commonly used protocols to transfer data between computers over the Internet.
However, despite being an old methodology, users still find it to be one of the best and most commonly used protocols, and users enjoy using it for uploading and downloading files in their day-to-day work. Setting up an FTP server on Linux is generally quite simple.
