Solution and Explanation
RAM (Random Access Memory) is the main memory of a computer used to store data and programs currently in use. It is volatile, meaning the data is lost when power is switched off.
ROM (Read Only Memory) is a permanent memory that stores essential instructions needed to start the computer. It is non-volatile and retains data even when the power is off.
The main differences are that RAM is temporary and volatile, while ROM is permanent and non-volatile. RAM allows both reading and writing of data, whereas ROM generally allows only reading.

- Dynamic RAM (DRAM) stores each bit of data in a separate capacitor. Due to leakage, the stored charge tends to dissipate over time and needs to be refreshed periodically. Consider the following statements: \[\begin{array}{rl} \bullet & \text{P: DRAM requires refreshing because it uses capacitors to store bits.} \\ \bullet & \text{Q: SRAM does not require refreshing because it uses flip-flops instead of capacitors.} \\ \bullet & \text{R: DRAM is faster than SRAM because it needs less frequent access.} \\ \bullet & \text{S: DRAM is more suitable for main memory than SRAM due to its density.} \\ \end{array}\]
