  9. 9. Hardware which converts information into one readable by the computer. Pointing Devices Mouse Trackball Touch Pad Pointing Stick Joystick Pen Input Digitizer Tablet Touch Screen Light Pen Keyboard Mic Scanner Digital Camera Video Camera/ Web cam Bar Code Reader Magnetic Card Reader Smart Card Reader Optical Mark Reader (OMR) Magnetic Ink Character Reader (MICR) 2.1 Input Device
  10. 10. Scroll mouse Wireless Keyboard 2.1 Input Device
  11. 11. Video Camera/ Web Cam Trackball 2.1 Input Device
  12. 12. A pointing stick is a pointing device that consists of a miniature joystick, usually with a rubber eraser-head tip, positioned somewhere between the keys on the keyboard. Most pointing sticks are pressure-sensitive, so the pointer moves faster when more pressure is applied. A touch pad allow for mouse movement simply by dragging a finger tip across a surface. 2.1 Input Device
  13. 13. The joystick is a rotary lever. Similar to an aircraft's control stick, it enables you to move within the screen's environment, and is widely used in the computer games industry. A Digitising Tablet is a pointing device that facilitates the accurate input of drawings and designs. A drawing can be placed directly on the tablet, and the user traces outlines or inputs coordinate positions with a hand-held stylus. 2.1 Input Device
  14. 14. A Light Pen is a pointing device shaped like a pen and is connected to a VDU. The tip of the light pen contains a light-sensitive element which, when placed against the screen, detects the light from the screen enabling the computer to identify the location of the pen on the screen. Light pens have the advantage of 'drawing' directly onto the screen, but this can become uncomfortable, and they are not as accurate as digitising tablets. A computer can read numbers and letters printed with ink containing magnetic material MICR is used by banks to process cheques. The account details at the bottom of the cheque can be accurately read in this manner since MICR is not affected by dirt. 2.1 Input Device
  15. 15. The Optical Mark Reader (OMR) can read information in the form of numbers or letters and put it into the computer. The marks have to be precisely located as in multiple choice test papers. A Touch Sensitive Screen is a pointing device that enables the user to interact with the computer by touching the screen. 2.1 Input Device
  16. 16. Hardware which converts data into one readable by human. Monitor (VDU) CRT LCD 2.2 Output Device
  17. 17. Regular CRT Near Flat CRT Flat Screen CRT The different types of CRT monitor 2.2 Output Device
  18. 18. <ul><li>Advantages of LCD monitor over CRT </li></ul><ul><ul><ul><li>Sleek, space-saving design. These new designs leave more room on your desk (and can be wall-mounted, too). </li></ul></ul></ul><ul><ul><ul><li>Ergonomic features. Reduced eye strain from a brighter, flicker-free screen with virtually no glare. </li></ul></ul></ul><ul><ul><ul><li>Better total cost of ownership (TCO). With twice the lifespan, one-third the electricity usage and minimal heat output compared to similar-sized CRT monitor. </li></ul></ul></ul><ul><ul><ul><li>Safety. LCDs are safer to use because they have no electromagnetic radiation. </li></ul></ul></ul><ul><li>Advantages of CRT monitor over LCD </li></ul><ul><ul><ul><li>Excellent Value. CRTs have come very inexpensive for entry-level models, and high-end full-featured displays are now more affordable than ever. </li></ul></ul></ul><ul><ul><ul><li>Precise images. CRTs provide exceptional detail for everything from CAD/CAM applications to word processing, spreadsheets and family photos. </li></ul></ul></ul><ul><ul><ul><li>Vibrant, realistic images . . . even in motion. A full spectrum of rich, saturated colors with incredible depth and superior video response make CRTs perfect for gaming, graphic design, or even watching TV with a ViewSonic video processor. </li></ul></ul></ul><ul><ul><ul><li>. </li></ul></ul></ul>2.2 Output Device

  23. 23. Plotter A large printer that generates high-quality documents by moving ink pens over the surface of a page. Plotters are particularly useful to engineers and architects, as they produce high-quality blueprints, maps, and floor plans. Also called an X-Y plotter. 2.2 Output Device

  29. 29. Safety & Electrostatic Precaution 3 Components of System Unit
  30. 30. Safety Precautions 1. Unplug power cables 2. Never wear jewelry or other metal objects 3. Avoid spills- never use liquids around electrical equipment. 4. Wear anti-static grounding wrist strap/ mat 5. Always place components in provided anti-static bag when not in use 6. Wear proper clothing - Cotton, Wool etc 7. Frames of casing may be sharp - be careful not to get cut 8. Replace any worn or damaged power cords immediately 9. Avoid using extension cords. 10. Do not attempt to fix PSU/ monitor- refer to qualified personnel 11. Replace blown fuse with one of similar rating and type. 3 Components of System Unit
