Console to Decryption

Console	See Terminal.
Cross-Over	A length of multi-stranded cable in which the transmit
	wire(s) of one end is/are crossed over within the cable to
	connect to the receive wire(s) of the other end. Cross-
	Overs are used to connect devices to like devices, ensuring
	that transmit and receive connections are properly made.
Crosstalk	A corruption of the electrical signal transmitted through a
	Shielded or Unshielded twisted pair cable. Crosstalk refers
	to signals on one strand or set of strands affecting signals
	on another strand or set of strands.
CSMA/CD	Carrier Sense Multiple Access with Collision Detection.
	CSMA/CD is the basis for the operation of Ethernet
	networks. CSMA/CD is the method by which stations
	monitor the network, determine when to transmit data, and
	what to do if they sense a collision or other error during
	that transmission.
Data	Information, typically in the form of a series of bits, which
	is intended to be stored, altered, displayed, transmitted, or
	processed.
Data Loop	A condition caused by the creation of duplicate paths
	which network transmissions could follow. Data loops are
	created by the use of redundant connections between
	network segments or devices. Ethernet networks cannot
	effectively function with data loops present. To allow the
	creation of fault-tolerant networks, data loops are
	automatically detected and eliminated by the Spanning
	Tree algorithm.
DB15	A 15-pin connector used to terminate transceiver cables
	in accordance with the AUI specification.
DB9	A 9-pin connector, typically used in Token Ring networks
	and for serial communications between computers.
Decryption	The translation of data from an encrypted form into a
	form both recognizable and utilizable by a workstation,
	node, or network device.
