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 data

is the computer system must be integrated by the software. This software is the so-called operating system (OS). Operating system gives an important role in computer system. This is a collection of system programs that controls the operation of a computer system. The purpose of this is to organize and control hardware and software so that the device it lives in behaves in a flexible but predictable way. This is the first thing loaded onto the computer.
