Computer Science - Computer Fundamentals - Discussion

CPU contains two parts:

One is ALU and other is CU.
ALU performs arithmetic and logic operations and CU controls the overall operations.
So CU is called the Brain of the computer.

CPU (Central Processing unit) is considered the brain of computer.

CPU is also called a Brain of the computer.

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.

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.

What is the heart of a computer ?

Recently I have seen a question. Please, Can anybody tell me the answer?

CPU is the brain of a computer. Mu, Cu & Alu are contained in the CPU.

Because for a computer to run it must located in the computer.

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 is the Central processing unit of the computer and it consist of CU, MU, and ALU which is called brain of the computer.
