CNET 184 - CH 3a
The device that bridges wireless networking components and a wired network.
Access Point Device
Hardware devices that increase the power of electrical signals to maintain their original strength when transmitted across a large network.
The method of signal transmission used on
A 2.5 Mbps LAN technology that uses token-based networking technology and runs over several kinds of coaxial cable, twisted pair, and fiber-optic cable.
Attached Resource Computing Network (ARCnet)
The weakening of a signal as it travels the length of a medium, which eventually causes the signal to be unreadable.
The part of the cable plant that interconnects telecommunications closets and equipment rooms.
The range of frequencies that a communications medium can carry.
A technology that uses digital signals sent over a cable without modulation. It sends binary values as pulses of different voltage levels.
An analog trasmission technique that can use multiple communication channels simultaneously.
A special-purpose networking device that permits a computer to send and receive networking signals, primarily for Internet access, by using to data channels on a broadband CATV network.
The combination of installed network cables, connectors, patch panels, wall jacks and other media components.
A nontransparent layer of glass or plastic material inside
A type of cable that uses a center conductor, wrapped by an insulating layer and surrounded by a braided wire mesh and an outer jacket or sheath, to carry high bandwidth signals.
A phenomenon that occurs when two wires lay against eachother in parallel.
A designation for cabling of any kind.
The use of two wires to carry a signal, where one wire carries a positive voltage signal and the other carries a negative.
A broadband technique in which 2 cables are used; one for transmitting and one for receiving.
A form of interference cause by emission from external devices that can disrupt network transmissions over an electrical medium.
Electromagnetic Interference (EMI)
The capability to "listen" to signals passing through a communications media by detecting its emissions.
An industry trade group of electronics and networking manufacturers that collaberates on standards for wiring, connectors and other common components.
Electronic Industries Alliance
The location of the cabling and equipment taht connects a corporate network to a third party telecommunications provider.
An area that serves as a connection point for backbone cableing running between telecommunications closets
A cabling technology that uses pulses of light sent along a light-conducting fiber at the heart of the cable to transfer information from sender to receiver.
An orbital position relative to Earth where a satellite orbits at the same speed as Earth rotates.
The weakening of signlas that occurs on a cable segment each time a network device is attached.
