Which of the following statement about computer memory are true?  A. Secondary storage is non-volatile storage.  B. Video memory found in graphics cards is volatile memory.  C. Primary memory (RAM) is the fastest form of memory in a computer.  Choose the correct answer from the options given below: Correct Answer A and B only 

Key Points
  • Non-volatile memory (NVM) is a type of computer memory that has the capability to hold saved data even if the power is turned off.
  • Secondary storage is non-volatile storage.
  • Unlike volatile memory, NVM does not require its memory data to be periodically refreshed.
  • It is commonly used for secondary storage or long-term consistent storage.
  • Video memory is memory on a video card and in some cases on the motherboard, that's accessible by the video and computer processor. Video memory found in graphics cards is volatile memory.
  • Video random access memory (VRAM) is dedicated computer memory used to store the pixels and other graphics data as a frame buffer to be rendered on a computer monitor. 
  • In some systems this memory cannot be read/written using the same methods as normal memory; it is not memory mapped.

Therefore, the correct answer is A and B only.

Additional Information

  • Cache memory is a small-sized type of volatile computer memory that provides high-speed data access to a processor and stores frequently used computer programs, applications, and data.
  • It is the fastest memory in a computer, and is typically integrated onto the motherboard and directly embedded in the processor or main random access 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.
