strengthening of a signal by a networking device
|
Detailed explanation-1: -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.
Detailed explanation-2: -Signal attenuation is the reduction or loss of communication signal strength during transmission, which is the mode of transferring data, such as an email or phone call. A signal refers to the current that transmits data from one network to another.
Detailed explanation-3: -What does the term “attenuation” mean in data communication? loss of signal strength as distance increases.
Detailed explanation-4: -Long cabling – Over a long distance, transmitted signals slowly lose strength. Wire size – Thin wires experience more attenuation than thicker wires because they are more vulnerable to external interferences.
