A Batch Operating System is a type of operating system that processes jobs in groups or batches without user interaction. Users submit jobs to the system, which then queues them for execution. This approach maximizes resource utilization by allowing the system to run multiple jobs sequentially, reducing idle time. In a batch system, jobs are typically processed based on priority or arrival time. The system automatically handles job scheduling and execution, making it efficient for tasks that require similar resources. Examples of batch processing can be found in mainframe computers and certain data processing applications.
