File Transfer Protocol (FTP) port 20 is a client/server protocol used for transferring files to or exchanging files with a host computer. It may be authenticated with user names and passwords. Anonymous FTP allows users to access files, programs and other data from the Internet without the need for a user ID or password.
Websites are sometimes designed to allow users to use ‘anonymous’ or ‘guest’ as a user ID and an email address for a password. Publicly available flies are often found in a directory called pub and can be easily FTP’d to a user’s computer. FTP is also the Internet standard for moving or transferring files from one computer to another using TCP or IP networks.
File Transfer Protocol is also known as RFC 959.« Back to Glossary Index
