(A1) Simple Batch Systems

Simple Batch systems or just Batch systems process jobs bundled together, leading to an increase in efficiency.

When a job is processed, the system transfers the entire control over to it. Once it is done, the control shifts to the next job, and so on.

This hence, has the following ADVANTAGES:

-maximum processor utilization
-the setup time for jobs is saved
-performance increases, since, the job are sequenced together

It also, however, has a few DISADVANTAGES:

-difficult to debug
-one job affects all the pending jobs.
- job could enter an infinite loop, and others will never be processed.

Hence, we would need some protection scheme for the pending jobs, in case a job is affected/corrupt.
