configuration.
Answer: shared
◉ Propagation delay is negligible with satellite transmission.
Answer: False
◉ Which is not true about point-to-point circuits.
Answer: point-to-point circuits reduce the amount of cable required

sound wave..
Answer: False
◉ With which type of digital signaling does the signal always return
to zero volts after each bit?.
Answer: Return-to-zero signaling
◉ Statistical time division multiplexing does not require the capacity
of the circuit to be equal to the sum of the combined circuits..
Answer: True
◉ The type of media usually installed on homes and businesses by
the telephone company is called ____________..
Answer: twisted pair
◉ Digital transmission occurs when the signal sent over the
transmission media constantly varies among an infinite number of
states..
Answer: False
,◉ Which type of digital signaling would experience fewer errors
because it has more distinct signals?.
Answer: bipolar
◉ WDM is a version of FDM used in fiber-optic cables..
Answer: True
◉ ______________ refers to the time it takes for a signal to travel from
sender to recipient (highly exaggerated with satellite transmission)..
Answer: Propagation delay
◉ Which of the following is the most secure wired media?.
Answer: Fiber-optic cable
◉ In which type of modulation is a 1 distinguished from a 0 by
shifting the direction in which the wave begins?.
Answer: Phase modulation
◉ ____________ is a modulation technique that combines two different
amplitude combinations with eight different phase combinations
modulation to send four bits per symbol..
Answer: Quadrature Amplitude Modulation
, ◉ A physical circuit refers to the transmission characteristics of the
connection..
Answer: False
◉ Multitasking means to break one high-speed physical
communication circuit into several lower-speed logical circuits so
that different devices can simultaneously use it..
Answer: False
◉ Which of the following media can best withstand harsh
environmental conditions?.
Answer: Fiber-optic cable
◉ One form of interference with satellite transmission is called
raindrop attenuation in which the transmissions are absorbed by
heavy rain..
Answer: True
◉ Having a conversation with someone using a cellular phone is an
example of _________ transmission..
Answer: full-duplex
◉ ____________ is used by IM and other applications that provide voice
services over lower-speed digital circuits..
