Disadvantages Of Serial Processing Operating System

Cost Batch processing is less expensive than online input. It uses very little computer processing time to prepare a batch of data; most of the computing occurs when the batch executes. At that time, a program reads thousands of simple data records from the batch file and processes them against a database. A computer that does only batch input does not need extra hardware and software required for interactive input.

Though cost savings were a strong argument for batch processing in the 1970s, the costs for online computing have fallen considerably since then. Most modern computer systems offer a mix of batch and online input. Scheduling Batch input takes place during a batch job, which is a computer file containing instructions to run programs and read batched input data. An operator submits the batch job as a one-time event or as a task to run automatically on a schedule.

The operator can, for example, schedule batch jobs to run at the end of the month to print reports for management. Most batch jobs are fully automated and can run during the day or in the middle of the night. The automated nature of batch jobs adds convenience for planning and scheduling work.
