T/F: Transmission methods using fiber-optic cables achieve faster throughput than those using copper or wireless connections.
T/F: In frequency modulation, the frequency of the carrier signal is modified by the application of the data signal.
T/F: An access point is a device that accepts wireless signals from multiple nodes and retransmits them to the rest of the network.
In cases in which signals may travel in only one direction, the transmission is considered ____.
A form of transmission that allows multiple signals to travel simultaneously over one medium is known as ____.
A(n) ____ is a piece of hardware that enables networks or segments running on different media to interconnect and exchange signals.
____ cable consists of color-coded pairs of insulated copper wires, each with a diameter of 0.4 to 0.8 mm.
____ cable consists of twisted wire pairs that are not only individually insulated, but also surrounded by a shielding made of a metallic substance such as foil.
____ is a measure of the highest frequency of signal a multimode fiber can support over a specific distance and is measured in MHz-km.
A patch cable in which the termination locations of the transmit and receive wires on one end of the cable are reversed is known as a(n) ____.
Networks that transmit signals through the atmosphere via infrared or radiofrequency (RF) waves are known as ____.
An antenna's ____ describes the relative strength over a three dimensional area of all the electromagnetic energy the antenna sends or receives.
Which of the following terms refers to a change in signal strength as a result of some of the electromagnetic energy being scattered, reflected, or diffracted after being issued by the transmitter?
In ____, a transmitter concentrates the signal energy at a single frequency or in a very small range of frequencies.
____ signals are transmitted by frequencies in the 300- GHz to 300,000-GHz range, which is just above the top of the wireless spectrum as it is defined by the FCC.
When a data transmission involves only one transmitter and one receiver, it is considered a(n) ____ transmission.
____ is the number of times that a wave's amplitude cycles from its starting point, through its highest amplitude and its lowest amplitude, and back to its starting point over a fixed period of time.
When signals are free to travel in both directions over a medium simultaneously, the transmission is considered _____.
_______ occurs when a signal traveling on one wire or cable infringes on the signal traveling over an adjacent wire or cable.
________ are the pieces of hardware that connect the wire to the network device, be it a file server, workstation, switch, or printer.
A panel of data receptors into which horizontal cabling from the workstations is inserted.
The nondata information that must accompany data for a signal to be properly routed and interpreted by the network.
Issues and receives wireless signals with equal strength and clarity in all directions.
A distinct communication path between nodes, much as a lane is a distinct transportation path on a freeway.
