Memory Management Mastery: A Virtual Memory, Paging, and Swapping Quiz Quiz

1. Virtual Memory Basics

   What is the primary purpose of virtual memory?

   1. To allow programs to use more memory than is physically available.
   2. To directly manage physical memory allocation.
   3. To replace the hard drive with RAM.
   4. To improve CPU processing speed.
   5. To decrease memory access time.

2. Paging Process

   In a paging system, what is a page?

   1. A fixed-size block of physical memory.
   2. A variable-sized block of virtual memory.
   3. A fixed-size block of virtual memory.
   4. A segment of code within a function.
   5. A unit of data transferred between CPU and cache.

3. Swapping Mechanics

   What is the main purpose of swapping in memory management?

   1. To move processes temporarily out of main memory to a backing store.
   2. To permanently delete processes from the system.
   3. To move data between different CPU registers.
   4. To directly increase the size of RAM.
   5. To exchange data between cache levels.

4. Page Table Structure

   What does a page table typically store?

   1. The mapping between virtual addresses and physical addresses.
   2. The size of the hard drive.
   3. The list of all running processes.
   4. The CPU's current instruction set.
   5. The network configuration settings.

5. Thrashing Scenario

   Which of the following best describes thrashing?

   1. A state where a process spends more time swapping pages than executing instructions.
   2. A technique for speeding up memory access.
   3. A process performing excessive I/O operations.
   4. A memory leak in a program.
   5. The physical damage of memory chips.

6. Translation Lookaside Buffer (TLB)

   What is the purpose of the Translation Lookaside Buffer (TLB)?

   1. To cache recent translations between virtual and physical addresses.
   2. To store the operating system kernel.
   3. To manage network connections.
   4. To buffer disk writes.
   5. To enhance CPU clock speed.

7. Page Fault Handling

   What action is triggered when a page fault occurs?

   1. The operating system retrieves the missing page from secondary storage.
   2. The system immediately crashes.
   3. The CPU switches to a different process.
   4. The current process is terminated.
   5. The cache memory is cleared.

8. Demand Paging Implementation

   What is demand paging?

   1. Loading pages into memory only when they are needed.
   2. Loading all pages into memory at the start of a process.
   3. Deleting pages from memory when they are no longer needed.
   4. Using a fixed-size page table.
   5. Allocating memory in contiguous blocks.

9. Page Replacement Algorithms

   Which of the following is a common page replacement algorithm?

   1. Least Recently Used (LRU).
   2. First Come First Serve (FCFS).
   3. Shortest Job First (SJF).
   4. Round Robin (RR).
   5. Highest Priority First (HPF).

10. Benefits of Virtual Memory

    Which of the following is a significant benefit of using virtual memory?

    1. Increased memory utilization and the ability to run larger programs than physical memory allows.
    2. Elimination of all memory management overhead.
    3. Direct access to physical memory without operating system intervention.
    4. Guaranteed prevention of memory leaks.
    5. Increased CPU clock speed.
