is an IEEE standard for LANs, that defines the physical layer as shielded twisted pair
and the MAC (medium access control) layer as Token Ring.
is a coded representation of the destination of a message.
see "Event."
stands for Address Resolution Protocol, which dynamically maps network addresses
to MAC addresses.

is a VT100 or compatible video display terminal.
stands for "asynchronous."

character stream; it also describes the protocol used to interconnect such devices.
is an async terminal connected to a serial port (configured as COM1), acting as an
operator console.
is a VT100 or compatible video display terminal.
is the default line speed code (throughput class) for async PAD ports. When a PAD
places a call through a port set to Autobaud, the port's internal clocks are set to match
the speed of the PAD.
