What is the name of the very fast memory that exists between the computer's RAM and the processor?

Correct option is A

Cache memory is a small, high-speed memory located close to the processor that stores frequently accessed data and instructions, enabling faster processing by reducing the time taken to access data from the main RAM.
Important Key Points:
1. Cache Memory:
· Acts as a buffer between the CPU and RAM.
· Stores frequently used instructions and data to speed up processing.
· Comes in levels: L1, L2, L3 (Level 1, 2, and 3 cache).
2. Importance: Improves overall system performance by minimizing the latency of memory access.
Knowledge Booster:
· Virtual Memory: A section of the hard drive used as temporary RAM when physical RAM is full. It is much slower than cache memory.
· Secondary Memory: Refers to storage devices like HDDs or SSDs, not directly involved in processing.
· Register: Extremely small and fast memory located within the CPU, used for temporary storage during processing.
· Flash Memory: A type of non-volatile memory used in devices like USB drives and SSDs.
