1 / 10

What is the purpose of a ready queue in CPU scheduling?

To manage printer jobs by queuing and scheduling them

To store metadata and information about a file

To hold processes that are ready to execute but are waiting for CPU time

To allocate memory to different processes

2 / 10

What is the role of a direct memory access (DMA) controller?

To manage the storage and retrieval of files

To allow certain hardware devices to transfer data directly to or from memory without involving the CPU

To provide an abstract representation of an opened file

To allocate memory to different processes

3 / 10

What is the purpose of a virtual machine (VM) in operating systems?

To provide an abstract representation of an opened file

To manage communication between hardware devices and the CPU

To create an isolated environment that emulates a physical computer and allows multiple operating systems to run concurrently on the same hardware

To allocate memory to different processes

4 / 10

What is the role of a monitor in concurrent programming?

To provide mutual exclusion and condition synchronization to protect shared resources

To manage communication between hardware devices and the CPU

To determine the priority of a process

To allocate memory to different processes

5 / 10

What is the purpose of a process control block (PCB) in operating systems?

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 store all the necessary information about a process, including its state, priority, and register values

6 / 10

What is the role of a logical AND operator in process synchronization?

To manage communication between hardware devices and the CPU

To synchronize the execution of multiple processes by ensuring that all of them reach a certain point before proceeding

To determine the priority of a process

To allocate memory to different processes

7 / 10

What is the purpose of a deadlock avoidance algorithm in operating systems?

To detect the presence of a deadlock and take corrective actions

To monitor the health and performance of a system

To prevent the occurrence of a deadlock by carefully allocating and managing resources

To determine the priority of a process

8 / 10

What is the purpose of a thread pool in concurrent programming?

To manage printer jobs by queuing and scheduling them

To allocate memory to different processes

To provide an abstract representation of an opened file

To manage and reuse a pool of threads to reduce the overhead of creating new threads for every task

9 / 10

What is the role of a kernel in operating systems?

To provide an abstract representation of an opened file

To manage communication between hardware devices and the CPU

To manage the storage and retrieval of files

To provide essential services and functions that enable applications and hardware to communicate with each other

10 / 10

What is the purpose of a spooling in operating systems?

To manage communication between hardware devices and the CPU

To allocate memory to different processes

To provide an abstract representation of an opened file

To store data in a buffer before sending it to an output device, allowing the CPU to continue working on other tasks
