27 Random Access Memory Questions And Answers

21⟩ Explain what is Virtual Memory?

This is a method of extending the available physical memory on a computer. In a virtual memory system, the operating system creates a pagefile, or swapfile, and divides memory into units called pages. Recently referenced pages are located in physical memory, or RAM. If a page of memory is not referenced for a while, it is written to the pagefile. This is called "swapping" or "paging out" memory. If that piece of memory is then later referenced by a program, the operating system reads the memory page back from the pagefile into physical memory, also called "swapping" or "paging in" memory. The total amount of memory that is available to programs is the amount of physical memory in the computer in addition to the size of the pagefile.

22⟩ Explain on what does microprocessor speed depend?

The processing speed depends on DATA BUS WIDTH.

Factors on which the Processor speed depends:

1) Processor clock speed

2) Processor pipelining

3) Width of the data and address bus, i.e. Max Data that can be fetched at one stretch.

4) Support for floating point operations for faster floating point operations.

26⟩ What is Static RAM?

No refreshing, 6 to 8 MOS transistors are required to form one memory cell, Information stored as voltage level in a flip flop. Dynamic RAM: Refreshed periodically, 3 to 4 transistors are required to form one memory cell, Information is stored as a charge in the gate to substrate capacitance.
