FTP, computer application used in the late 20th and early 21st centuries to transfer files from one computer to another over a local area network (LAN) or a wide area network (WAN) such as the Internet.
First proposed by engineers in 1971 and developed for use on host computers at the Massachusetts Institute of Technology, FTP allowed for reliable and swift exchange of information between computers with different operating systems and machine architectures.
FTP advanced along with computer technology throughout the 1970s and ’80s, becoming an international standard in 1985. In the 1990s the World Wide Web’s hypertext transfer protocol (HTTP) began taking over as the chief means of exchanging smaller text and image files between computers over the Internet.
The open design of FTP, while revolutionary, posed a security risk that was not considered important in the 1970s when users were on LANs within one organization. FTP sent all information as plain text, which meant that user names, user passwords, and commands sent over a network could be intercepted, read, and exploited by cybercriminals. In 2021 the popular Web browsers Google Chrome and Mozilla’s Firefox removed support for FTP.
