Batch Operating System in OS

Batch Operating System

Batch Operating system groups jobs that perform similar type of functions. These groups are treated as a batch and are executed at the same time. A computer system with this type of operating system carries out the following activities related to batch processing:

• A job is defined as a single unit which is made up of a predefined sequence of commands, data, and programs.
•  These jobs are kept in a memory executing them without manual information.
• Processing is done in the order in which they are submitted, i.e., first come first serve.
•   The operating system releases memory of a job as soon as it is executed successfully.
• An executed job is kept in an output spool for further printing or processing.

Advantages of Batch Processing

• It relieves the operator from the manual assignment of jobs.
• These operating system offer high performance as the next job is executed as soon as the previous job is finished.

Disadvantages of Batch Processing

• Its program is difficult to debug.
• A job can enter into an infinite loop.
• If a big job enters a processor, it might cause a delay for the next jobs in the queue.
• Shorter jobs may have to wait for longer duration if a longer job enters the processor.

Examples

• Hadoop
• Spark

The most significant part of the Batch processing system is, it requires minimal human intervention for processing.
