Batch Operating System
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. The programmers leave their programs with the operator
and the operator then sorts the programs with similar requirements into batches.
The problems with Batch Systems are as follows:
Lack of interaction between the user and the job.
CPU is often idle, because the speed of the mechanical I/O devices is slower than
the CPU.
