What is trivial file transfer protocol? Explain briefly?

Trivial File Transfer Protocol (i.e. TFTP) is helpful for bootstrapping a hardware device which does not have a disk on that to store system software. Each device requires is a network connection and a small amount of ROM (read only memory) in which UDP, IP and TFTP are hardwired. Even though, TFTP is less powerful than file transfer protocol (FTP). Trivial File Transfer Protocol does have two advantages. Primary, TFTP can be utilized in environments where UDP is available, but TCP is not. Next is the code for TFTP needs less memory than the code for FTP.
