Answers Explanation & Hints: Goodput is a term used to describe the measure of usable data that is transferred over a communication channel in a given amount of time. It is a measure of the actual data transfer rate that takes into account factors such as retransmissions and protocol overhead.
In other words, goodput refers to the actual useful data that is delivered from the source to the destination over a communication channel, excluding any retransmissions, acknowledgments, or other overheads that are necessary for reliable data transmission.
Goodput is typically measured in bits per second (bps) or bytes per second (Bps) and is affected by various factors such as the available bandwidth, latency, and packet loss on the communication channel.
In communication systems, goodput is an important metric as it determines the actual amount of useful data that can be transmitted over a given channel in a given amount of time. For example, in a video streaming application, goodput is the actual amount of video data that is delivered to the user in real-time, taking into account any retransmissions or other overheads that may be necessary for reliable data transmission.
In summary, goodput is a measure of the actual data transfer rate that takes into account the usable data that is transferred over a communication channel, excluding any retransmissions or other overheads. It is an important metric in communication systems as it determines the actual amount of useful data that can be transmitted over a given channel in a given amount of time.
