	Coaxial to Decryption
Coaxial	An Ethernet media type which consists of a core of electrically conductive
	material surrounded by several layers of insulation and shielding.
Concentrator	A network device which allows multiple network ports in one location to
	share one physical interface to the network.
Congestion	An estimation or measure of the utilization of a network, typically
	expressed as a percentage of theoretical maximum utilization of the
	network.
Connectivity	The physical connection of cabling or other media to network devices.
	The coupling of media to the network.
Crossover	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. Crossovers 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 (see encryption) form into a
	form both recognizable and utilizable by a workstation, node, or network
	device.
