Then what is the execution time?

Seek time - time taken for an access arm to get into position over a particular track.

Head switching - this is the activation of a particular read and write head over a particular track.

Rational delay - time for waiting until the desired data on the track rotates under the read and write head.

Please explain.

Real time is a level of computer responsiveness that a user senses as sufficiently immediate or that enables the computer to keep up with some external process.

On the level of machine language, the operation of the CPU is fairly straightforward. The CPU executes a program that is stored as a sequence of machine language instructions in main memory.

It does this by repeatedly reading, or fetching, an instruction from memory and then carrying out, or executing, that instruction. This process -- fetch an instruction, execute it, fetch another instruction, execute it, and so on forever -- is called the fetch-and-execute cycle.

Please explain Delay time, Real time and seek time.

Thanks for clear explanation.

Could you explain the seek time and real time and delay time?

A narrative technique whereby events are depicted as occurring entirely within the span of and at the same rate as the depiction.

Does CPU cycle stands for central processing unit cycle?
