Final answer:
The bandwidth-delay product, representing the maximum number of bits that can be in transit in a link, is calculated as Bandwidth times Delay.
Step-by-step explanation:
The maximum number of bits that can reside inside a link between the sender and receiver is known as the bandwidth-delay product. This is calculated by multiplying the bandwidth of the link by the delay (latency) of the link. Given that the bandwidth measures how much data can be sent per second, and delay is the amount of time it takes for a single bit to travel from sender to receiver, the formula for the bandwidth-delay product is Bandwidth x Delay.
