100
The radius of the maximum arc into which you can loop a cable before you will cause data transmission errors. Generally, a twisted pair cable’s ______ is equal to or greater than four times the diameter of the cable.
What is bend radius
100
A standard for coaxial cable connectors named after its coupling method and its inventors.
What is BNC (Bayonet Neill-Concelman, or British Naval Connector)
100
A system founded on using 1s and 0s to encode information.
What is Binary
100
A device that boosts, or strengthens, an analog signal.
What is amplifier
100
equals a single pulse in the digital encoding system. It may have only one of two values: 0 or 1.
What is bit (binary digit)
200
A measure of a signal’s strength.
What is amplitude
200
A measure of the difference between the highest and lowest frequencies that a medium can transmit.
What is bandwidth
200
A form of UTP that contains four wire pairs and supports up to 100-Mbps throughput and a 100-MHz signal rate.
What is CAT-5
200
Abbreviation for the word category when describing a type of twisted pair cable.
What is CAT
200
A transmission that involves one transmitter and multiple, undefined receivers.
What is broadcast
300
The glass or plastic shield around the core of a fiber-optic cable. _______ reflects light back to the core in patterns that vary depending on the transmission mode. This reflection allows fiber to bend around corners without impairing the light-based signal.
What is Cladding
300
A coaxial cable connector type that uses a twist-and-lock (or bayonet) style of coupling. It may be used with several coaxial cable types, including RG-6 and RG-59.
What is BNC connector
300
The pieces of hardware that connect the wire to the network device, be it a file server, workstation, switch, or printer.
What is connectors
300
A modulation technique in which the amplitude of the carrier signal is modified by the application of a data signal.
What is AM (amplitude modulation)
300
The extent to which a signal has weakened after traveling a given distance.
What is attenuation
400
Eight bits of information. In a digital signaling system, broadly speaking, one ______ carries one piece of information.
What is Byte
400
A signal that uses variable voltage to create continuous waves, resulting in an inexact transmission.
What is analog
400
A type of cable that consists of a central metal conducting core, which might be solid or stranded and is often made of copper, surrounded by an insulator, a braided metal shielding, called braiding, and an outer cover, called the sheath or jacket.
What is coaxial cable
400
The pipeline used to contain and protect cabling. Is usually made from metal or sometimes PVC.
What is conduit
400
A distinct communication path between two or more nodes, much as if a lane is a distinct transportation path on a freeway. _______ may be separated either logically (as in multiplexing) or physically (as when they are carried by separate wires).
What is channel
500
A standard rating that indicates the diameter of a wire, such as the conducting core of a coaxial cable.
What is AWG (American Wire Gauge)
500
A form of transmission in which signals are modulated as radiofrequency analog pulses with different frequency ranges. Unlike baseband, _________ technology does not involve binary encoding. The use of multiple frequencies enables a _________ system to operate over several channels and, therefore, carry much more data than a baseband system
What is broadband
500
EMI interference induced on one cable by signals traveling over a nearby cable.
What is alien cross talk
500
A form of transmission in which digital signals are sent through direct current pulses applied to a wire. This direct current requires exclusive use of the wire’s capacity, so ________ systems can transmit only one signal, or one channel, at a time. Every device on a _______ system shares a single channel.
What is baseband
500
A braided metal shielding used to insulate some types of coaxial cable.
What is braiding
