In this type of system the user make pakages of jobs and store them in a punch card for offline store and then pass it to the computer operator and then the computer operator makes batches of the jobs that require similar resources to process.
Simple batch operating system. In this type of system there is no direct interaction between user and. In multi programmed system the cpu switches to second job and begins to execute it. Types of operating system.
Similarly when second job needs to wait the processor is switched to third job and so on. In this the operating system picks up and begins to execute one. In a simple batch system or non multi programmed system the processor would sit idle.
When the job is complete its output is usually printed on a line printer for example. Some main memory is now given over to the monitor some processor time is consumed by the monitor despite overhead the simple batch system improves utilization of the computer. Performed by the batch monitor resided in the low end of main memory.
