What is the full form of FTP in computer terminology ?

Networking acronyms used in computer terminology are formal, standardized abbreviations — each letter maps to one specific word defined in the governing standard (an RFC, in this case), so the correct expansion must match that official wording exactly, not merely sound plausible.

FTP stands for File Transfer Protocol, defined in RFC 959. It is an application-layer protocol used to move files between a client and a server over a TCP/IP network: a control connection (typically on port 21) manages commands and login, while a separate data connection carries the actual file contents.

Checking each option word-for-word against the official name:

• "File Transferred Protocol" uses the past-tense word "Transferred" in place of the standard term "Transfer".

• "Form Transfer Protocol" replaces "File" with "Form", naming a different object (an input form or document) rather than a file.

• "File Transmission Protocol" substitutes "Transmission" for "Transfer" — a related but distinct networking word that does not match the official RFC 959 name.

Only "File" paired with "Transfer" reproduces the official name defined in RFC 959, so the standard expansion of FTP is File Transfer Protocol.
