An operating system (OS) is basically a collection of software that manages computer hardware resources and provides common services for computer programs. Operating system is a crucial component of the system software in a computer system.
Batch Operating system is one of the important type of operating system.
The users who using a batch operating system do not interact with the computer directly. Each user prepares its job on an off-line device like punch cards and submits it to the computer operator. To speed up the processing, jobs with similar needs are batched together and run as a group. The programmers exit their programs with the operator and the operator then sorts the programs with similar requirements into batches.
The problems that occurs with Batch Systems are as follows −
There is a lack of interaction between the user and the job.
CPU is being often idle, because the speed of the mechanical I/O devices is slower than the CPU.
It is difficult to provide the desired priority.
