The CPU (central processing unit) is the part of the computer that does most of the work. It contains arithmetic and logic parts that can do millions of calculations per second.
The CPU is what executes program instructions, which, at the CPU level, are instructions that are directly to the hardware.

It is called the brain, I suppose, because it actually does the work that programs require. All other parts of the computer are controlled by the CPU and without it the computer doesn't work (much like a human brain).
