What are the differences between cache and RAM?

Cache and RAM are both types of memory used in computers, but they serve different purposes. Cache is faster and smaller, used to store frequently accessed data, while RAM is larger and slower, used for temporary data storage during active processes.

Why is cache memory faster than RAM?

Cache memory is faster because it is located closer to the CPU and is designed to provide quick access to frequently used data, reducing the time it takes to retrieve information compared to RAM.

How does the size of cache affect performance?

A larger cache can store more data, which can improve performance by reducing the number of times the CPU has to access slower RAM. However, there's a point of diminishing returns where increasing cache size yields less performance benefit.

Can I upgrade my cache memory?

Cache memory is typically built into the CPU and cannot be upgraded separately. However, you can improve overall performance by upgrading RAM or the CPU itself.
