What is the role of a CPU burst time in process scheduling?

To manage communication between hardware devices and the CPU

To determine the priority of a process

To provide an abstract representation of an opened file

To represent the amount of time a process spends executing before it's preempted and moved to the ready queue

2 / 10

What is the purpose of a master boot record (MBR) in disk storage?

To store metadata and information about a file

To contain the boot loader and partition table information for the storage device

To manage communication between hardware devices and the CPU

To provide an abstract representation of an opened file

3 / 10

What is the role of a scheduler in operating systems?

To manage communication between hardware devices and the CPU

To determine the priority of a process

To select the next process from the ready queue to be executed by the CPU

To allocate memory to different processes

4 / 10

What is the purpose of a virtual address in memory management?

To represent a location in the address space of a process

To translate virtual addresses to physical addresses

To manage communication between hardware devices and the CPU

To represent the location of a memory cell in physical memory

5 / 10

What is the role of a job queue in job scheduling?

To store metadata and information about a file

To provide an abstract representation of an opened file

To manage communication between hardware devices and the CPU

To hold all the processes that are waiting to be executed

6 / 10

What is the purpose of a round-robin scheduling algorithm?

To manage printer jobs by queuing and scheduling them

To determine the priority of a process

To allocate a fixed time slice to each process in a cyclic order, ensuring fairness

To synchronize and control access to shared resources among multiple processes

7 / 10

What is the role of a swap space in virtual memory management?

To determine the priority of a process

To store metadata and information about a file

To provide an abstract representation of an opened file

To temporarily store pages that are not in main memory, allowing the system to free up space for other tasks

8 / 10

What is the purpose of a file system buffer cache?

To manage communication between hardware devices and the CPU

To store metadata and information about a file

To allocate memory to different processes

To cache recently used data blocks to reduce the number of disk reads and improve I/O performance

9 / 10

What is the role of a deadlock prevention algorithm?

To prevent the occurrence of a deadlock by ensuring that the necessary conditions for deadlock are never met

To detect the presence of a deadlock and take corrective actions

To determine the priority of a process

To monitor the health and performance of a system

10 / 10

What is the purpose of a context switch in operating systems?

To manage communication between hardware devices and the CPU

To provide an abstract representation of an opened file

To switch the CPU from one process to another and save the state of the current process

To allocate memory to different processes
