What is the full form of TFTP?

The correct answer is Trivial File Transfer Protocol, which is a simplified version of the standard File Transfer Protocol (FTP). TFTP is used primarily for transferring small amounts of data, such as configuration files or firmware updates, between devices on a network. It operates over the User Datagram Protocol (UDP), which does not establish a connection before data transfer and does not guarantee delivery. This makes TFTP a lightweight option ideal for scenarios where simplicity and speed are prioritized over reliability.

TFTP's simplicity is evident in its lack of complex features such as authentication and directory browsing, which makes it suitable for environments where ease of implementation is more critical than advanced functionalities. This protocol is commonly employed in network environments, such as when routers and switches need to load configuration files or firmware images during the initialization process.

Other options, while seemingly plausible, do not reflect the actual terminology used in networking contexts.
