Transmission impairment in computer network
A) High network traffic
B) Network topology
C) Signal attenuation and noise
D) Network protocols
Answer:
C) Signal attenuation and noise
Explanation:
Transmission impairment in computer networks is primarily caused by signal attenuation (weakening of the signal as it travels over long distances) and noise (unwanted interference or disturbances in the signal). These factors can lead to data errors and affect the quality of network communication.
