Question 49 Explanation:
Virtual memory: Not physical memory itself, but rather a memory management technique that uses disk storage to extend the apparent size of main memory.
Cache memory: A small, fast memory that stores frequently accessed data from main memory to speed up access times. It’s not considered part of main memory, but rather a separate layer between the CPU and main memory.
RAM (Random Access Memory): The primary, volatile memory that directly stores programs and data currently in use by the CPU. It’s the core of main memory.
SSD (Solid State Drive): A non-volatile storage device that can be used as main memory in some systems, offering faster access times than traditional hard drives. It’s becoming increasingly common as main memory, especially in high-performance systems.
