CPU contain hard disk, RAM, graphics card, microprocessor. All processing units are include. So CPU is brain of all computer.

Benard Ouma Owino said: (Sep 16, 2014)  
Can you please give a brief description of what the ALU, CUI and MU are?

Jean-Luc said: (Sep 26, 2014)  
In biology, the nervous system controls the activities of the brain. That is similar with the Motherboard and the CPU. It perform, s task as storing, executing, Performs mathematical operations and equally controls the output of processed data.

Sanny said: (Sep 27, 2014)  
What are the functions of ALU, CU & MU ?

Surtan said: (Oct 11, 2014)  
CPU is the memory actually because it has CU (control unit). Though we have computer memory unit (MU) like : registers, cache level 1 and level 2, ram, ROM. CU in the CPU, control all this. The control unit is connected with northern and southern bridge which makes data flow successful. ALU is in CPU it performs all arithmetic and mathematical computation. The clock is in CPU it assign time to each operation (process) that is being processed.

CPU consists of several units which performs specific tasks such as registers, bus interfaces and transfers the data between computer and peripherals.

Ayuka Moses said: (Oct 1, 2016)  
CPU is the brain of a computer. Mu, Cu & Alu are contained in the CPU.

John said: (Oct 10, 2016)  
CPU the best answer b/e CPU is the central processing unit of the computer and it consist of 'CU' control both input and output device of the computer 'MU' store large information 'ALU' perform arithmetic and logical. So, it is called brain of the computer.

Sharvan Ranga Kaithal said: (Dec 26, 2016)  
The working of cpu in m. P is similar to working of the brain in human.

And operating system~nervous system.

So CPU (mu, cu. Alu) ~brain + heart.

And operating system~nervous system+mind (both mind & op. System can't seen).

Siddique said: (Jan 6, 2017)  
Cpu is a brain of the computer because over all parts is connected to CPU.

Zeeshan Abbasi said: (Mar 13, 2017)  
The CPU is the brain of computer and ALU is the component of CPU.

Tanay Dey Td said: (Aug 18, 2017)  
CPU= Central Processing Unit.

It's a Microprocessor (It's a chip). It contains millions of transistors which help in manipulate data. There's an ALU (arithmetic-logic unit) part which performs calculation within seconds. Also, CU (Control Unit) gives the result of execution (as taking input and instruction from a program it respond for output).

Further, the ALU is divided into two units, an arithmetic unit (AU) and a logic unit (LU). You may say a CPU as the decision maker.

In simple language, Fetching Instruction from Main Memory to CU, then decoding instruction into command, ALU help to execute the program and again it stores in the memory. A complete cycle goes on.

Taniya Sahu said: (Oct 24, 2017)  
All computer operator like a mouse, keybord are connected to cpu. Cpu is handling all operators and control like human brian so computer brain is cpu.

Computerspecialist.Com said: (Nov 6, 2017)  
CPU stands for central processing unit.

Babu said: (Nov 28, 2017)  
Why not ALU?

Pushpat Mahatara said: (Jul 19, 2019)  
CPU stands for Central Processing Unit.
