What is the purpose of a file descriptor in Unix-like operating systems?

To store metadata and information about a file

To manage communication between hardware devices and the CPU

To provide an abstract representation of an opened file

To allocate memory to different processes

2 / 10

What is the role of a I/O scheduler in operating systems?

To manage the execution of processes in the CPU

To determine the priority of a process

To optimize the order in which I/O requests are serviced to improve overall system performance

To manage communication between hardware devices and the CPU

3 / 10

What is the purpose of a TLB (Translation Lookaside Buffer) in virtual memory?

To manage communication between hardware devices and the CPU

To store recently used pages and their corresponding physical addresses for faster access

To allocate memory to different processes

To manage the storage and retrieval of files

4 / 10

What is the role of a logical address in memory management?

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

To represent a location in the address space of a process

5 / 10

What is the purpose of the 'nice' command in Unix-like operating systems?

To determine the priority of a process

To allocate memory to different processes

To manage the storage and retrieval of files

To provide user interfaces for applications

6 / 10

What is a multi-level queue scheduling algorithm?

A scheduling algorithm that assigns each process a fixed time slice in a round-robin manner

A scheduling algorithm that assigns priority levels to processes and each level is scheduled using a different algorithm

A scheduling algorithm that selects the process with the shortest execution time next

A scheduling algorithm that uses both first-come-first-served and round-robin techniques

7 / 10

What is the role of a deadlock detection algorithm in operating systems?

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

To manage communication between hardware devices and the CPU

8 / 10

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

To manage printer jobs by queuing and scheduling them

To provide an abstract representation of an opened file

To allocate memory to different processes

To enable a single process to have multiple execution paths and share resources

9 / 10

What is the role of a page fault in virtual memory management?

To manage the storage and retrieval of files

To allocate memory to different processes

To handle situations where a requested page is not in main memory and needs to be brought in from secondary storage

To manage communication between hardware devices and the CPU

10 / 10

What is the purpose of a semaphore in operating systems?

To manage communication between hardware devices and the CPU

To allocate memory to different processes

To synchronize and control access to shared resources among multiple processes

To provide user interfaces for applications
