You have 3 levels of cache, cache is a small amount of very speedy static RAM near the processor.

Level 1: inside the processor, same speed as him. small size, very fast
Level 2: outside the chip, same or half speed as the processor, bigger
Level 3: outside the chip, bigger still

Instructions, data etc are going to the processor thru these caches, giving time to the system to gather these and store them for the processor in time for the proc not to wait before doing its job. No time wasted! And the computer is faster than if it was relying only on the normal RAM only.

An old but enlightning explaination page can be found HERE
