as a buffer between the computer processor and the display and is often called the frame buffer.
Answer option D is incorrect. DRAM is a standard RAM type for PCs and laptops.

FactWhat is the function of SRAM? Hide
Static Random Access Memory (SRAM) is used for a computer’s cache memory and as part of the
random access memory digital-to-analog converter on a video card. Unlike DRAM, SRAM does not
have to be periodically refreshed. SRAM retains data bits in its memory as long as power is being
supplied. SRAM is significantly faster and more expensive than DRAM.
