Default CPU Architecture

Hey guys, can someone explain to me what the different parts of a CPU are used for? I have a basic knowledge like FSB and clock speed but things like L2 cache seem to elude me.

L2 cache, and any other cache in the CPU itself, act as a buffer for the CPU's intructions. Just as hard drives have a buffer, the processor needs a buffer to store instructions that it cannot complete right when it gets them. This lets the processor be more efficient and can save clock cycles by storing commonly used instruction inside the CPU.
Hope that helped.
