What do you mean by Trivial File Transfer Protocol?

TRIVIAL FILE TRANSFER PROTOCOL (TFTP)

There are occasions when we need to simply copy a file without the need for all of the functionalities of the FTP protocol. For example, when a diskless workstation or a router is booted, we need to download the bootstrap and configuration files. Here we do not need all of the sophistication provided in FTP. We just need a protocol that quickly copies the files.

Trivial File Transfer Protocol (TFTP) is designed for these types of file transfer. It is so simple that the software package can fit into the read-only memory of a diskless workstation. It can be used at bootstrap time.

TFTP can read or write a file for the client. Reading means copying a file from the server site to the client site. Writing means copying a file from client site to the server site.
