What is the difference between SRAM and DRAM?Each correct answer represents a complete solution. Choose two.

The correct answer is B. SRAM has in-built switches and does not have to be refreshed but DRAM needs to be C. SRAM is faster than DRAM. Static Random Access Memory (SRAM) has in-built switches that do not have to be refreshed. Dynamic Random Access Memory (DRAM) uses capacitors instead of switches that need constant refresh signals to keep information in the memory. DRAM requires more power than that of SRAM…

Explanation

Static Random Access Memory (SRAM) has in-built switches that do not have to be refreshed. Dynamic Random Access Memory (DRAM) uses capacitors instead of switches that need constant refresh signals to keep information in the memory. DRAM requires more power than that of SRAM, therefore, SRAM is mostly used in desktop computers. With an access time of 15 to 30 nanoseconds, SRAM is faster than DRAM that has an access time of 80 nanoseconds or more.
