Question

The heart of a computer is
A. CPU
B. Memory
C. Input
D. None of these

Answer 1

Hint: A computer is an electronic machine. It accepts the input, stores and manipulates data, and provides output in the desired form. Computers or any electronic devices understand two values which are zeros and ones which form the Binary Language (0 and 1).

Complete Step-by-step answer:The part of the computer that performs program instruction is known as the processor or central processing unit (CPU). It is the Heart of the computer, the component that executes the instruction. In a microcomputer, the CPU is on a single electronic component, the microprocessor chip, within the system unit or system channel. The system unit also contains a circuit board, memory unit, hard disk, etc. The CPU has two parts: Control Unit and Arithmetic Logic Unit (ALU).

Control Unit (CU): The control unit tells the rest of the computer how to perform a program’s instruction. It instructs the movement of electronic signals between memory which temporarily holds data, instruction, and processed instruction, and the ALU. It also directs these control signals between the input/output devices and the CPU.

Arithmetic Logic Unit (ALU): Arithmetic Logic unit, commonly called ALU, runs two types of operation. Arithmetic and Logical operation. The Arithmetic operation is the functional mathematical operation that consists of addition, subtraction, multiplication, and division. The Logical Operation is composed of comparison. That is two pieces of data are compared to see whether one is equivalent to, smaller than, or bigger than the other

Memory: Memory which is also known as primary storage or main memory, is a part of the microcomputer that holds data for processing, instructions for processing the data and information. The capacity of the memory to hold data and program instruction varies in various computers.

Input:Any information or data sent to a computer for processing is considered as input. Input or user input is fed into a computer using an input device.




Therefore the correct answer is Option A.

Note: All kinds of computing devices like tablets, PCs, or laptops feature a brain-like unit referred to as a central processing unit or CPU. The computer’s CPU computes and interprets instructions while browsing the web, creating documents, playing games, or running software applications.
