VIRTUAL MEMORY QUIZEZZS

What is the primary purpose of virtual memory in computer systems?

• Increase CPU clock speed

• Expand the physical RAM capacity

• Improve disk storage performance

• Enhance the efficiency of program execution

What is the primary advantage of demand paging in operating systems?

• Increased system throughput

• Reduced memory wastage

• Faster program startup times

• Enhanced security

What is the name of a metric used in demand paging for accessing memory?
(Hint : Effective Accessing Time)

(a)  

What does "instruction restart" in virtual memory refer to?

• Terminating the program when a page fault occurs.

• Resuming the program's execution from the beginning after a page fault.

• Re-executing the instruction that caused a page fault after loading the required page into memory.

• Ignoring the page fault and proceeding with the next instruction.

In the context of virtual memory, what is the purpose of the valid-invalid bit?

• To indicate whether a page is present in secondary storage

• To specify the size of the virtual memory space

• To determine the order of page replacement

• To mark whether a page in virtual memory is currently valid or invalid

Why is handling a page fault crucial in virtual memory management within operating systems?

• To increase the physical memory capacity

• To prevent memory leaks in the program

• To efficiently use more memory than physically available

• To minimize the need for secondary storage

How many step in handling page fault ?

• 8

• 6

• 12

• 10

(GENERAL QUESTION)

When does the virtual memory first commercial computer release ?

• 1959

• 1960

• 1961

• 1962

In virtual memory systems, what is the purpose of page replacement?

• To decrease the page size

• To improve disk storage performance

• To manage the translation lookaside buffer

• To free up space in physical memory for incoming pages

Which algorithm is commonly used for page replacement in virtual memory systems to decide which page to remove when a page fault occurs?

• Least Recently Used (LRU)

• First-In-First-Out (FIFO)

• Shortest Job Next (SJN)

• Round Robin
