What does the term attenuation mean in data communication?
A. loss of signal strength as distance increases
B. strengthening of a signal by a networking device
C. time for a signal to reach its destination
D. leakage of signals from one cable pair to another
The correct answer for the term attenuation mean in data communication is: A. loss of signal strength as distance increases
Explanation: When a signal, whether it is simple or composite, travels through a medium, it experiences attenuation, which is a loss of energy. This occurs because the signal must overcome the resistance of the medium in order to move through the medium.
This is the reason why, after some time has passed, a wire that is transmitting electric impulses would get warm, if not hot. During the transmission of the signal, a portion of the electrical energy is transformed into heat. In order to make up for this particular loss, amplifiers are utilised in order to magnify the signal.
