What term describes the ratio of useful information bits to total transmitted bits?

Explanation:
Transmission efficiency measures how effectively a link carries useful information. It’s the ratio of useful information bits (the payload) to the total bits transmitted, including all overhead such as headers, error-correcting codes, and preambles. For example, if a frame has 200 payload bits and 800 bits of overhead, the efficiency is 200/1000 = 0.2 (20%). This concept focuses on how much of the transmitted data is actually useful, unlike bandwidth (channel capacity in bits per second), throughput (actual payload data rate achieved), or latency (delay).
