This is a collection of protocols based on the ones used by the US defence
department and are now widely used in private networking and the
Internet.
TELNET:
A protocol which governs the exchange of Character Orientated data,
allowing a terminal to communicate with a remote host.
TERMINAL ADAPTOR:
A device which converts from one protocol to another, to allow a computer
using one protocol to connect to a computer using a different protocol.
