What is the difference between cache and main memory?
Cache memory is a small, high-speed storage area located close to the CPU, while main memory (RAM) is larger and slower.
Why is cache memory faster than main memory?
Cache memory is faster because it uses static RAM (SRAM) which is quicker to access than the dynamic RAM (DRAM) used in main memory.
How does the CPU decide what to store in cache?
The CPU uses algorithms to predict which data will be needed soon, storing frequently accessed data in cache for faster retrieval.
Can I increase the cache size in my computer?
Cache size is typically fixed and determined by the CPU architecture, but you can upgrade your CPU for a larger cache.
What happens if the cache is full?
If the cache is full, the CPU will use a replacement policy to remove less frequently used data to make space for new data.
