What does the term “attenuation” mean in data communication?
- loss of signal strength as distance increases
- time for a signal to reach its destination
- leakage of signals from one cable pair to another
- strengthening of a signal by a networking device
Answers Explanation & Hints:
Data is transmitted on copper cables as electrical pulses. A detector in the network interface of a destination device must receive a signal that can be successfully decoded to match the signal sent. However, the farther the signal travels, the more it deteriorates. This is referred to as signal attenuation.
