- Latency
- Wherever there is latency, what arrives now reflects what happened earlier, so the present output is always a delayed image of a past input.
This sourceEstablishes latency as a distinct quantity from bandwidth/throughput that improves far more slowly across technologies, and motivates the traversal-time-versus-capacity distinction and the use of buffering/prefetching to hide irreducible delay.
