It is also responsible for logical calculations like comparisons among data items. It performs all the arithmetical calculations and computations like addition, subtraction, multiplication and division. The CPU ensures the flow of data into the system by directing the data to enter the system, storing it into the memory and retrieving it when needed to produce the output. While some input devices are designed for special purposes such as Optical Character Recognition (OCR), Magnetic Ink Character Recognition (MICR) and Bar Code Reader etc, there are other devices that accept input by responding to physical touch and voice such as ATMs.

The commonly used input devices are mouse, keyboard, light pen, optical scanner etc. Input unit is responsible for controlling the various input devices that are used to enter data into the computer. The relationship among these components is well established by the following diagram: These components are the building blocks of a computer and define its architecture. describes all parts of the system that are reused (for example, processors and IP Com- ponents). Input Unit, Central Processing Unit and Output Unit. Components of A Computer System :Ī computer system mainly has three components viz.

This sharing is possible using wires, cables, satellite, infra-red, Bluetooth, microwave transmission etc. When two or more computers are connected to each other, they can share information and resources such as sharing of files (data/music etc.), sharing of printer, sharing of facilities like the internet etc.

Processed and useful data is called information which is used for decision making. Data is raw until the computer system interprets it using machine language, stores it in memory, classifies it for processing and produces results in conformance with the instructions given to it. The facts and figures that are fed into a computer for further processing are called data. It maintains the overall internal working of each part of a computer system by directing the flow of information.
