What is the difference between L1, L2, and L3 cache?
L1, L2, and L3 caches are types of CPU cache memory that store frequently accessed data to speed up processing. L1 is the fastest and closest to the CPU, while L3 is larger but slower.
Can you explain the size and speed differences between them?
Sure! L1 cache is typically 32KB to 64KB, L2 is 256KB to 1MB, and L3 can be several megabytes. L1 is the fastest, followed by L2, and then L3.
Why is having multiple levels of cache important?
Multiple cache levels help balance speed and size. L1 is fast but small, while L3 is larger but slower, allowing for efficient data retrieval.
How does cache affect overall system performance?
Cache significantly improves system performance by reducing the time the CPU takes to access data from the main memory, leading to faster processing.
