Correct Answer: B
Explanation/Reference:
Explanation:
Latency is a measure of the time required for a sub-system or a component in that sub-system to process a single storage transaction or data request. It’s akin to the propagation delay of a signal through a discrete component and is typically a function of hardware. For storage subsystems, latency refers to how long it takes for a single data request to be received and the right data found and accessed from the storage media.
