Which of the following memory types is typically used for the CPU's Level 1 (L1) cache? MCQ with Answer and Explanation

Explanation:
RAM (Random Access Memory) is volatile, meaning it loses its contents when power is turned off. ROM, hard disk, and CD-ROM are non-volatile.

Explanation:
While L1 and L2 caches are generally dedicated to individual CPU cores, the L3 cache is larger, slightly slower, and shared across all cores on the processor die.

Explanation:
DDR4 common CAS latencies are around 14-16, though higher speeds may have CL18-22. DDR3 had CL9-11. DDR5 is higher (CL30+). So A is correct for typical DDR4.
