Xerox 490 ST Telnet, Thicknet, Thinnet, Token passing, Token Ring, Transceiver, Type 1 cable

Telnet	TCP/IP protocol governing character-oriented terminal data.
Thicknet	Cabling scheme using twin axial cable.
Thinnet	Cabling scheme using 50 ohm coaxial cable.
Token	The character sequence passed among nodes in sequence to indicate
	which one has permission to transmit.
Token passing	Network access method that requires nodes to wait for their turn
	before transmitting data. Turns are indicated by a character
	sequence that passes from one node to the next.
Token Ring	A 4 megabit per second or 16 megabit per second network using a
	ring topology and a token passing access method.
Transceiver	An AUI (Attachment Unit Interface) device for receiving and
	transmitting data that often provides collision detection as well.
twisted pair cable	A wiring scheme with one or more pairs of 18 to 24 gauge copper
	strands are twisted to improve protection against electromagnetic
	and radio frequency interference. Cable may be either shielded or
	unshielded.
type 1 cable	Shielded two-pair cable.
type 3 cable	Unshielded twisted-pair cable.
type 5 cable	Shielded twisted-pair cable.
WAN (Wide Area	A network capable of transmissions over large geographic areas that
Network)	uses transmission lines provided by a common-carrier.
workstation	A networked computer typically reserved for end-user applications.
Zone	One or more connected AppleTalk networks grouped according to
	network usage.
