4. What is a context switch, and why is it necessary in process scheduling?

A context switch is the process of saving and restoring the state of a CPU to allow multiple processes to share the same CPU. It is necessary to switch between processes efficiently.

A context switch is a type of error in process scheduling.

A context switch is a process of switching between different operating systems.

A context switch is a mechanism to increase the speed of process execution.

5. What is 'thread-safe' in the context of programming and multithreading?

A type of thread that is always safe to use

A program that only uses a single thread

A program that can be executed by multiple threads simultaneously without issues

A program that never crashes

6. Which component of an operating system's user interface allows users to interact with files and folders?

Task Manager

Control Panel

File Explorer (or File Manager)

Start Menu

7. What is 'thread synchronization' in operating systems?

Synchronizing threads to run at the same time

Ensuring that threads share data and resources in a controlled manner

Synchronizing the system clock with an atomic clock

Terminating threads that are not responding

8. What is the purpose of process priority in process scheduling?

Process priority determines the order in which processes are executed. Higher-priority processes are given preference over lower-priority ones.

Process priority is used to create new processes in the operating system.

Process priority controls the speed of the CPU.

Process priority is used for file management in the operating system.

9. What is the purpose of process scheduling in an operating system?

To organize files on the hard disk

To create user interfaces

To manage device drivers

To allocate CPU time to different processes

10. What is 'context switch' in the context of process management?

Switching between different keyboard layouts

Switching between user accounts

Switching between different operating systems

Switching between processes or tasks in the CPU

11. Explain the concept of process scheduling in an operating system.

Process scheduling involves deciding which process to run next on the CPU, allowing multiple processes to share the CPU's time.

Process scheduling is the process of creating a new process in the operating system.

Process scheduling is used to format the text displayed on the screen.

Process scheduling is the process of shutting down a process.

12. What does RAM stand for in the context of computer memory?

Random Access Memory

Read-Only Memory

Remote Access Memory

Revolving Access Memory

13. What is 'zombie process' in the context of process management?

A process that has been infected by a computer virus

A process that is running at maximum CPU speed

A process that has terminated but still has an entry in the process table

A process that consumes excessive memory

14. What is a process in the context of operating systems?

A program in execution

A type of computer virus

A peripheral device

A system configuration file

15. What is 'deadlock' in the context of process management?

A process that has terminated successfully

A situation where two or more processes are unable to proceed because each is waiting for the other

A process that is running at maximum CPU speed

A process that is consuming excessive memory

16. What is the purpose of virtual memory in an operating system?

To store virtual reality content

To provide a virtual workspace for users

To create virtual machines

To expand the available physical memory by using a portion of the hard disk

17. What is the main purpose of the 'Task Manager' in Windows?

To play games

To create documents

18. What is 'process scheduling' in operating systems?

Scheduling appointments for computer users

Scheduling regular software updates

Scheduling tasks for the CPU to execute

Scheduling hardware maintenance

19. What is a 'shell' in the context of operating systems?

A protective case for computer hardware

A user interface for interacting with the operating system

A type of file format

A type of hardware device

20. Explain the concept of process termination in an operating system.

Process termination is the process of ending the execution of a process. It involves releasing allocated resources and cleaning up the process's state.

Process termination is the process of creating new processes in the operating system.

Process termination is the process of formatting the screen in the operating system.

Process termination is the process of switching between processes.
