NOTES
:
BATCH OPERATING SYSTEM:

The users of batch operating system do not interact with the computer directly. Each user prepares his job on an off-line device like punch cards and submits it to the computer operator. To speed up processing, jobs with similar needs are batched together and run as a group. Thus, the programmers left their programs with the operator. The operator then sorts programs into batches with similar requirements.

The problems with Batch Systems are following.

Lack of interaction between the user and job.

CPU is often idle, because the speeds of the mechanical I/O devices is slower than CPU.

Difficult to provide the desired priority.
