Explain the concept of a batch operating system and how it works.
A batch operating system is a type of operating system where users submit their jobs to the computer operator, who then groups similar jobs together and runs them as a batch. The users do not directly interact with the computer. This system is efficient for processing large volumes of similar jobs, but lacks user interaction and can result in CPU idle time.
