  1. 1. NAME ;- HARDIK CLASS; 6TH A2 ROLL NO.;- NINE SUBJECT;- COMPUTER TOPIC ;- INPUT AND OUTPUT DEVICE SUBMITTED TO ;- SUNITA MAM
  2. 2. Input and Output Devices HARDIK 6TH A2
  3. 3. What is it? • Input devices are like raw data entered into the computer • Then it processes the data and produces outputs that we can understand • Processing is mainly handled by the CPU (Central Processing Unit)
  4. 4. Input Devices • There are two types of input devices, there are so many input devices that they are separated. • There is a Manual Input device and an Automatic Input device
  5. 5. Manual Input devices • Manual Input devices are devices which we have to work out ourselves. They are not automatic and there can be mistakes. Examples: • Keyboards: Alphanumeric Keyboard, Numeric keyboard and Pin pad
  6. 6. • Audio/ Visual Devices Scanner, digital camera, video camera, webcam, microphone • Pointing Devices: used in GUIs Mouse, Touchpad/trackpad, trackball/tracker ball, touch screen, graphics tablet, joystick, joypad, light pen
  7. 7. Automatic Input Devices All data can be put into a computer using a keyboard, but would often be slow and there could be mistakes. Automatic input devices can never be wrong, because it is accurate. Examples: • Card readers: Magnetic strip reader, smart card/ ‘chip’ reader,
  8. 8. • Reading Text/codes: MICR reader, OMR scanner, OCR scanner, barcode reader/scanner • Sensors Analogue to Digital Converter (ADC)
  9. 9. Output Devices • The computer communicates with the user by an input device • From an input device, the CPU processes it and its results are on the output device. • Output formats are usually printed paper, sound, video and on-screen documents.
  10. 10. Examples • Audio Visual: CRT monitor, Flat-screen Monitor (TFT or LCD), digital/multimedia projector, speakers. • Printing/Plotting: (hardcopy) Dot Matrix Printer, inkjet printer, laser printer, plotter,
  11. 11. • Control Actuators: An actuator is a device controlled by the computer that can affect the real-world Motor, pumps, buzzer, lights, heaters/coolers
