- What are the problems associated with batch operating systems?(Solved)
The users of a 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.

The programmers leave their programs with the operator and the operator then sorts the programs with similar requirements into batches.
