INTRODUCTION TO HARDWARE :
               in the previous class we have already studied the definition of computer and its basic components, we will review them here.
"A computer is an electronic machine which processes raw data  (Input) into meaningful information (output) and also stores output for later use."
A computer works with the help of its components. The components of  a computer consist of hardware and software.
       Components of a computer
1.  Software
2.  Hardware

SOFTWARE:
                      Software is the set of instructions given to the computer to perform specific task. A software is also called a computer program. For example , Microsoft windows, Ms word, core draw, device drivers, etc.
HARDWARE:
                       The physical parts of the computer that we can see and touch are known as hardware. These include the input and output devices as well as the system unit.
. Input devices:
                           Devices which are used to enter data Into a computer are known as input devices,e.g. keyboard, mouse, microphone, scan
ner, digital camera, etc.
.   OUTPUT DEVICES:
                                     Devices which are used to display / present output are called output devices, e.g. monitor, printer, speakers, etc.
.    Storage devices:
                                  Storage devices hold data and instructions permanently e.g. floppy disk, hard disk, CD/DVD, USB flash drive, etc.
COMMUNICATION DEVICES:
                                                   Devices which are used to communicate and connect a computer with other computers are known as communication devices e.g. modem.
