List and briefly describe the different types of operating systems.

Batch Operating System: This type of operating system does not interact with the computer directly. The user prepares a sequence of commands, it is then submitted to the system, and the computer processes the batch jobs when processor time becomes available.

Time-Sharing Operating Systems: Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time, mass storage, printing, and other resources.

Distributed Operating System: Distributed systems use multiple central processors to serve multiple real-time applications and multiple users. Data processing jobs are distributed among the processors accordingly.

Network Operating System: Network Operating Systems are designed to manage and coordinate network resources and services. They provide features such as file sharing, printer access, and email.

Real-Time Operating System: Real-time operating systems are used to control machinery, scientific instruments and industrial systems. They have an event-driven or time-sharing design and often aspects of both.

Mobile Operating System: This is the operating system that operates a smartphone, tablet, PDA, or other digital mobile devices. Examples include Android, iOS, and Windows Phone.
