Final answer:
Bandwidth and goodput are the terms that represent the maximum and actual speed that can be utilized by a device to transfer data.
Step-by-step explanation:
The terms that represent the maximum and actual speed that can be utilized by a device to transfer data are bandwidth and goodput.
Bandwidth refers to the maximum amount of data that can be transmitted over a network or communication channel in a given period of time. It measures the capacity of the channel and is usually expressed in bits per second (bps) or megabits per second (Mbps).
Goodput, on the other hand, refers to the actual throughput achieved by a device or network after accounting for factors such as protocol overhead and transmission errors. It represents the useful data transferred in a certain amount of time and is also expressed in bits per second (bps) or megabits per second (Mbps).
