Answer / guest
Answer: D
"Latency, which is measured using a "
Ping"
command, represents the delay that a message/packet will
have in traveling from source to destination. A decrease in
amplitude as a signal propagates through a transmission
medium is called attenuation. Throughput, which is the
quantity of work per unit of time, is measured in bytes per
second. Delay distortion represents delay in transmission
because the rate of propagation of a signal along a
transmission line varies with the frequency."
