A batch operating system is a type of operating system that processes jobs in groups or batches without user interaction. Users submit their jobs, which are collected and executed sequentially by the system. This approach maximizes resource utilization and minimizes idle time, as the system can efficiently manage multiple tasks. In a batch operating system, jobs are typically processed based on priority or arrival time. The system uses a job scheduler to determine the order of execution. This method is particularly useful for tasks that require significant processing time, such as data analysis or large-scale computations.
