What Is Correct About Virtual Memory?


Correct Answer: A) Virtual memory is the space on the hard drive where the OS begins to store data when it starts operation.



What is the advantage of virtual memory management?

The main advantage of virtual memory is that an OS can load programs larger than its physical memory. It makes an impression to the users that the computer has unlimited memory. It also provides memory protection. In order to realize the mapping operations, virtual memory needs to use page tables and translations.


What is correct about virtual memory?

Correct Answer: A) Virtual memory is the space on the hard drive where the OS begins to store data when it starts operation.


How does virtual memory differ from physical memory?

The main difference between physical and virtual memory is that the physical memory refers to the actual RAM of the system attached to the motherboard, but the virtual memory is a memory management technique that allows the users to execute programs larger than the actual physical memory.


Where is the swap space exists?

Explanation: Swap space exists in secondary memory.


Which are the benefits of virtual memory Mcq?

D. Virtual memory allows a process to run using a virtual address space which is larger in size then the address of physical memory and pages are swapped in between physical memory and virtual memory when physical memory gets full.


Where is virtual memory located?

Virtual memory is an area of a computer system's secondary memory storage space (such as a hard disk or solid state drive) which acts as if it were a part of the system's RAM or primary memory. Ideally, the data needed to run applications is stored in RAM, where they can be accessed quickly by the CPU.


Why do we need virtual memory?

Virtual memory serves two purposes. First, it allows us to extend the use of physical memory by using disk. Second, it allows us to have memory protection, because each virtual address is translated to a physical address.


Which algorithm chooses the page?

FIFO (First in First out) Page Replacement Algorithm − It is one of the simplest page replacement algorithm. The oldest page, which has spent the longest time in memory is chosen and replaced. This algorithm is implemented with the help of FIFO queue to hold the pages in memory.


What is true about ordinary files?

These files represent physical device like disks, terminals, printers, networks, tape drive etc. Explanation: Ordinary files : These are the files that contain user information.


What is the reusable resource?

reusable resource A resource, such as a CPU or tape transport, that is not rendered useless by being used. A magnetic disk or tape can be used often indefinitely and are to be regarded as reusable resources. Compare consumable resource. A Dictionary of Computing.


What is a role and responsibility of virtual memory?

Virtual memory is a feature of an operating system that enables a computer to be able to compensate shortages of physical memory by transferring pages of data from random access memory to disk storage. This process is done temporarily and is designed to work as a combination of RAM and space on the hard disk.


Are registers faster than L1 cache?

CPU register is always faster than the L1 cache.


Which of the following supports virtual memory?

Which of the following support virtual memory? Explanation: The paging mechanism supports the virtual memory. Paging helps in creating virtual address space which has a major role in memory management. 12.


What is a virtual memory miss called?

Page fault” in virtual memory is similar to “miss” in cache.


Which of the following statement is correct about virtual memory in MCQ question?

Which of the following statements is correct about virtual memory? Explanation: Virtual memory is used to separate the user's logical memory and actual physical memory. Therefore, option (b) is the correct answer.


What is the logical sequence of carbon cycle?

Thus, the correct answer is 'Producer → Consumer → Decomposer. '


Which one is the secondary storage device Mcq?

The correct answer is Hard Disk. Hard Disk is a secondary storage device in a computer.


Which of the following storage is fastest?

N/A

  • Fastest memory is cache memory.
  • Registers are temporary memory units that store data and are located in the processor, instead of in RAM, so data can be accessed and stored faster.


Is utorrent a presentation program?

Answer. Answer: Slide Panel is the correct answer.


What is the value of resistance of the resistor Mcq?

The correct answer is Ohm (Ω). Resistance is a measure of the opposition to current flow in an electrical circuit.
