This document provides an overview of basic computer concepts, including definitions of data, information, data processing, hardware, and software. Data is defined as raw facts, while information is processed data used for decision-making. It also distinguishes between input and output devices and outlines the role of system and application software in operating computer hardware.

3. Data
Data is collection of raw facts and figures .
Data is collected by different sources .
It may consist if pics , videos , documents , etc
.
Data plays an important role in computer.

4. Information
Information is defined as proceed form of
data.
It is used to make important decisions .
It is a output given by computer .
It is more meaningful and use form of data .

5. Data Processing
 The processing of converting data into useful information is called data processing.
 It includes basic step :
input
Input processing output

6. Hardware
 Any computer component that can be seen or touched is called hardware.
 A computer cannot perform any task without hardware .
 There are many types of hardware which are being used in daily life .
 The output is given through hardware .
 Monitor
 Keyboard
 Mouse
 Printer
 hard disk

7. Components of Hardware
Input Devices
 The data given to the computer for processing is called input .
 The device through which data is given to the computer is called input devices.
 These are some of :
Microphone
Keyboard
Mouse

8. Output Devices
 The devices that gives the user output is called output devices.
 The output is given after the processing of data .
 There are some examples of output devices :
 Monitor
 Speakers
 Printers

9. Software
 The instruction or a set of instructions given to the computer to perform any task is
called is software .
 There many numbers of software's available easily.
 Different software are used for different purposes .
 There are two kinds of software :
software
System
software
Application
software

10. System software
 System software is used to control and manage the operations of computer
hardware .
 It controls and allocated the computer hardware .
