TFTP can be implemented in a very small amount of memory. It is useful for booting computers such as routers which did not have any data storage devices. It is used to transfer small amounts of databetween hosts on a network, such as IP phone firmware or operating system images when a remote X Window System terminal or any other thin client boots from a network host or server.

The initial stages of some network based installation systems (such as Solaris Jumpstart, Red Hat Kickstart and Windows NTs Remote Installation Services) use TFTP to load a basic kernel that performs the actual installation. TFTP uses UDP port 69 for communication.
