Term
fiber optic
Definition
A medium comprised of minuscule strands of transparent glass or plastic that transmit data via signals of light.
Term
multi-mode (MMF)
Definition
A type of fiber optic cabling designed to allow transmission of multiple data channels.
Term
single-mode (SMF)
Definition
A type of fiber optic cabling designed to allows transmission of a single data channel.
Term
CAT3 cable
Definition
A standardized type of twisted pair cabling that maintains reliable throughput at speeds of up to 10Mbps with only a few twists per foot of cable.
Term
CAT5 cable
Definition
A standardized type of twisted pair cabling that maintains reliable throughput at speeds of up to 100Mbps.
Term
CAT5e cable
Definition
A standardized type of twisted pair cabling that maintains reliable throughput at speeds of up to 1Gbps.
Term
CAT6e cable
Definition
A standardized type of higher-quality twisted pair cabling that maintains reliable throughput at speeds of up to 10Gbps.
Term
composite cable
Definition
A type of cabling that consists of different types of transmission cables bundled together within the same wiring jacket.
Term
coaxial cable
Definition
A type of cable comprised of a solid core surrounded by a layer of insulation material, then covered in a layer of braided wire or foil, and finally wrapped in an insulating sheath. Variants of this cable type are often used in conjunction with television and video devices.
Term
serial cable
Definition
A type of cable that can be used to directly connect two computers, although transmission speeds are very low
Term
simplex
Definition
A mode of data transfer operation that allows transmission of data in one direction only
Term
half-duplex
Definition
A mode of data transfer operation that allows transmission of data in both directions, but only one direction at a time
Term
full-duplex
Definition
A mode of data transfer operation that allows transmission of data in both directions simultaneously
Term
attenuation
Definition
The degradation of a signal as it travels over distance
Term
RG-58
Definition
The type of coaxial cable used for Ethernet networking.
Term
RG-59 and RG-6
Definition
The two types of coaxial cable used for low-power video, cable television, and radio frequency signals, not to be confused with the type used in Ethernet networking.
Term
thicknet
Definition
The term for the coaxial cable used in 10Base5 networking.
Term
thinnet
Definition
The term for the coaxial cable used in 10Base2 networking.
