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.

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.

OH my dears first you should know what the brain is, which consist of short term sensory memory STSM (buffers in CS) ; Short term working memory STWM (RAM in CS) and Long term memory (hard disk in CS) and cognitive processor Glands (CPU in CS). So till now is CPU has all of above? but ecologically we use the brain as data storage location directly cluing to memory of CS.

CPU, the control processing unit consists of:

1. Arithmetic logic unit (ALU).
2. Control unit.
3. Memory unit.

Hence, all the functions like carrying out arithmetic operation, executing programs, passing out control over various functions and handling protocol, etc are carried out by CPU which is further controlled by operating system, installed in the system.

The central processing unit is commonly called the CPU. There 3 components of the CPU. They are control unit, Arithmetic & logic UNIT(ALU) The storage or memory. CPU is the heart of the entire computer system. CPU is responsible for processing the input & converting it into output.

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.

CPU has the ALU which manages logical operations and arithmetic calculations and the CU which controls all the computer peripherals. This therefore postulates that the CPU manages the working of the whole computer just like the brain manages the body.

CPU is the heart of the computer why because of the all computations will be done by the CPU.

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

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.
