Q. Explain about Batch System?

A number of computer systems only did one thing at a time. They had a list of computer system can be dedicated to a single program till its completion or they can be dynamically reassigned among a collection of active programs in various stages of execution.
Batch operating system is one where data and programs are collected together in a batch before processing starts. A job is predefined sequence of commands, data and programs which are combined in to a single unit known as job.

Fig. belowportrays memory layout for a simple batch system. Memory management in batch system is very simple. Memory is generally divided in two areas: User program area andOperating system.

Scheduling is simple also in batch systems. Jobs are processed in the order of submission which means first come first served fashion.

When a job finishes execution, its memory is released and output for the job gets copied in an output spool for later printing.

Batch system generally provides simple forms of file management. Access to file is serial. Batch systems don't need any time critical device management.

Batch systems are inconvenient for users since users can't interact with their jobs to fix problems. There can also be long turnaround times.
