What is cache memory usage and how does it affect performance?

Cache memory is a small-sized type of volatile memory that provides high-speed data access to the processor. It stores frequently accessed data and instructions, which helps improve overall system performance.

How does cache memory differ from RAM?

Cache memory is faster and smaller than RAM. While RAM stores data for active processes, cache memory holds the most frequently used data to speed up access times.

What happens when cache memory is full?

When cache memory is full, the system uses a cache replacement policy to remove the least recently used data, making space for new data.

Can I increase my cache memory?

Cache memory is typically built into the CPU and cannot be increased. However, optimizing your system's RAM and storage can improve overall performance.

What are the different levels of cache memory?

There are usually three levels of cache: L1 (smallest and fastest), L2 (larger and slightly slower), and L3 (largest and slowest). Each level serves to bridge the speed gap between the CPU and RAM.
