Answer:
b. P2 requests drive 2 and gets it.
Explanation:
Two users from the local board of education are each running a program (P1 and P2), and both programs will eventually need two DVD drives to copy files from one disc to another. Only two DVD-R drives are available and they’re allocated on an "as requested" basis. Soon the following sequence transpires: P2 requests drive 2 and gets it.
Answer:
Crosstalk, Jitter, Impulse noise.
Explanation:
Crosstalk is a network error that occurs when one pair of cable causes interference on another pair of cables thereby preventing efficient data transmission.
Jitter may also impair the accuracy of the data being transmitted across network because minute variations in amplitude, phase, and frequency always occur. The generation of a perfect carrier signal in an analog circuit is almost impossible. The signal may be affected by continuous and rapid network gains or phase changes.
Impulse noise (also referred to as spikes) is the primary source of errors in data communications. Impulse noise can be caused by positioning a communications cable near a source of intermittent but strong electromagnetic pulses, such as an elevator motor.
Counter measures
Shielding (protecting wires by covering them with an insulating coating) is one of the best ways to prevent impulse noise, cross-talk.
Amplifiers can be used to increase signal strength since the connection would run across 4 floors.
