MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -The correct answer is Both SRAM and DRAM are random access memory. Random-access memory comes in both SRAM and DRAM varieties. Both RAMs were developed to give different programmes access to data storage. A form of RAM known as SRAM (Static Random Access Memory) saves data bits in the memory when it is powered on.

Detailed explanation-2: -Static RAM is fast and expensive, and dynamic RAM is less expensive and slower. Therefore static RAM is used to create the CPU’s speed-sensitive cache, while dynamic RAM forms the larger system RAM space.

Detailed explanation-3: -SRAM is commonly used for a computer’s cache memory, such as a processor’s L2 or L3 cache. It is not used for a computer’s main memory because of its cost and size. Most computers use DRAM instead because it supports greater densities at a lower cost per megabyte (MB).

Detailed explanation-4: -c)Dynamic RAMs require a memory refresh cycle after each memory read cycle. d)Main memory of a general purpose computer system is usually built using dynamic RAMs. Correct answer is option ‘B’.
