Question : 109 of 120

Marks: +1, -0

Dynamic RAM (DRAM) stores each bit of data in a capacitor. Due to leakage, the stored charge dissipates over time and must be refreshed periodically. Consider the statements:
P: DRAM requires refreshing because it uses capacitors to store bits.
Q: SRAM does not require refreshing because it uses flip-flops instead of capacitors.
R: DRAM is faster than SRAM because it needs less frequent access.
S: DRAM is more suitable for main memory than SRAM due to its higher density.
Which option is correct?

$P$ and $S$ are true; $Q$ and $R$ are false
All statements $P, Q, R$ , and $S$ are true
Only $P$ and $Q$ are true; $R$ is false, and $S$ is irrelevant
$P, Q$ , and $S$ are true; $R$ is false
