What is batch operating system?

A batch operating system is a type of operating system that processes and executes tasks in batches, rather than allowing users to interact with the system in real-time. In a batch operating system, users submit jobs or tasks to be processed by the system, and the system processes these jobs in a sequential order without user intervention. This type of system is commonly used in mainframe computers and is efficient for processing large volumes of similar tasks. Examples of batch operating systems include IBM's z/OS and Unix/Linux batch processing systems.
