with spooling where the CPU overlaps the input of one job with the computation and of other jobs. ( Prefetching is a method of overlapping the I/O of a job with that job’s own computation. After a read operation completes and the job is about to start operating on the data‚ the input device is instructed to begin the next read immediately. The CPU and input device are then both busy. With luck‚ by the time that the job is ready for the next data item‚ the input device will have finished reading that
