CPU Registers are the fastest memory as they are part of the CPU and used for immediate data manipulation. Cache memory is faster than RAM because it acts as a buffer between the CPU and RAM, holding frequently accessed data. RAM is faster than secondary storage but slower than cache. Secondary storage is used for long-term data storage and is the slowest.
