Gopher

Many of them are owned by universities in various parts of the world. Most of them are neglected and rarely updated except for the ones run by enthusiasts of the protocol. Some have suggested that the bandwidth-sparing simple interface of Gopher would be a good match for mobile phones and PDAs, but so far, WML& WAP, DoCoMo i-mode, XTHTML Basic or other adaptations of HTML and XML, have proved more popular. The Py Gopherd server, however, provides a built-in WML front-end to Gopher sites served with it.
TFTP
Trivial File Transport Protocol (TFTP) is a very simple file transfer Protocol, with the functionality of a very basic form of FTP; it was first defined in 1980. Because it is so simple, it is easy to implement in a very small amount of memory which was an important consideration at that time. TFTP was therefore useful for booting computers such as routers which did not have any data storage devices. It is still used to transfer small amounts of data between 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 such as a network host or server. The initial stages of some network...
