The central processing unit (CPU) is the brain of your computer. CPU is the electronic circuitry within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logical, control and input/output operations specified by the instructions.
Following are the prime components of CPU:
- The arithmetic logic unit (ALU), which performs arithmetic and logical operations.
- The control unit (CU), which extracts instructions from memory and decodes and executes them, calling on the ALU when necessary.

Does the term CPU and system unit mean the same thing?

No. The CPU means Central Processing Unit. This is the main processor of the computer. A system unit is the hole unit (or personal computer).


What is the other name of system unit?

It is often incorrectly called the CPU or processor. Some call it the "brains" of the computer. These days, the "system unit" is the main part of the computer, the "box" part of it. To be more specific, "motherboard" may be the term you are looking for, and it is the main part of the computer located inside the case.

How many main parts of a computer?

It depends how far down the rabbit hole you wish to travel. At the top most level the basic computer has a motherboard which houses the basic components of a computer, you can have the CPU, Memory, BIOS, GPU, Network card, and a soundcard. Along with alot of other components. Not all of the above are necessary and in all computers. Even lower down the rabbit hold you can get into the sub components such as the MTU and others. But assuming CPU, Memory, BIOS, GPU, Network card, and a soundcard are the core components should stter you wrong.
