command processing overhead time

computer science, computing - the branch of engineering science that studies (with the aid of computers) computable processes and structures

access time - (computer science) the interval between the time data is requested by the system and the time the data is provided by the drive; "access time is the sum of seek time and rotational latency and command processing overhead"

processing time - the time it takes to complete a prescribed procedure; "they increased output by decreasing processing time"
