What does "batch" refer to in the context of computers executing a set of programs?

In computer terminology, "batch" refers to the execution of a set of programs in sequence rather than simultaneously. This means that the system processes a collection of tasks or jobs one after the other, typically without user interaction during the execution. This method is often used for jobs that do not require immediate user feedback and can be processed automatically, making it efficient for handling large volumes of data or tasks that need to be completed in a specific order.

Batch processing is widely utilized in environments where tasks are queued up and executed at predetermined times or based on specific conditions, such as in data processing, report generation, or batch jobs in computer systems. It contrasts with other methods, like real-time processing, where immediate execution is necessary, or parallel processing where tasks run simultaneously. Thus, understanding batch execution is crucial for optimizing resource usage and ensuring that operations are completed efficiently within a system.
