NIMCET 2020 — Computer PYQ

Solution

Comparison of DRAM and SRAM:

Feature	Dynamic RAM (DRAM)	Static RAM (SRAM)
Technology	Uses Capacitors to store data	Uses Flip-flops (Transistors)
Power Consumption	Less (due to simpler structure)	More (requires constant power)
Speed	Slower (requires refreshing)	Faster (no refreshing needed)
Cost	Cheaper	Expensive

Step 1: Power Consumption

DRAM stores data in capacitors which leak charge and require periodic refreshing. However, because it uses fewer components per bit, it generally consumes less power compared to SRAM, which uses multiple transistors to maintain a stable state.

Step 2: Speed

SRAM is significantly faster than DRAM because it does not require a refresh cycle and has lower latency. Therefore, DRAM is slower than SRAM.

Final Answer:

Dynamic RAM consumes Less Power and is Slower than Static RAM.

The correct combination is Less, Slower.
