### (i) DRAM Vs. SRAM

DRAM (Dynamic Random Access Memory):

* Volatile memory (loses data when power is off).
* Requires periodic refresh cycles to retain data.
* Slower access time compared to SRAM.
* More cost-effective and denser, allowing for higher storage capacity in smaller spaces.
* Commonly used for main memory in computers.

SRAM (Static Random Access Memory):

* Volatile memory, but doesn’t require refresh cycles like DRAM.
* Faster access time than DRAM.
* More expensive and takes up more space per bit of data stored, resulting in less capacity.
* Used for cache memory and in applications requiring faster data access.
