Questions & Answers

Q: What are the main tasks of process management in an operating system?

Process management involves loading, executing, suspending, resuming, and terminating processes. It also includes the ability to switch among multiple processors and prioritize processes based on their importance.

Q: How does an operating system handle I/O management?

I/O management ensures that I/O devices are shared among users without exposing hardware details. It also involves managing and controlling I/O devices, handling I/O requests, and providing a unified interface for accessing devices.

Q: What is the role of memory management in an operating system?

Memory management maximizes memory utilization, keeps track of memory usage, and allocates and deallocates memory for processes. It also manages memory devices, such as cache or buffers, to improve performance.

Q: How does file storage management work in an operating system?

File storage management involves manipulating, creating, and deleting files and directories. It includes allocating and deallocating memory blocks, marking bad blocks, and optimizing performance by scheduling and managing multiple I/O requests.

Summary & Key Takeaways

• Process management: an operating system should be able to load, execute, suspend, resume, and terminate processes, as well as switch among multiple processors.

• I/O management: the operating system should manage and share I/O devices among users, hide hardware details, and control I/O devices.

• Memory management: the OS should maximize memory utilization, track memory usage, allocate and deallocate memory, and manage memory devices.

• File storage management: the OS should manipulate, create, and delete files and directories, allocate and deallocate blocks of memory, mark bad blocks, and optimize performance.

• Protection: the OS should protect hardware and kernel resources, process code and data, and defend against malicious programs.

• Networking: the OS should support client-server or distributed systems, allowing for task sharing and resource management among multiple users.

• Command interpreter: the OS should provide a user-friendly interface for executing commands, accessing resources, and calling system programs or calls.
