Input and Output Devices Class V

  1. 1. INPUT AND OUTPUT DEVICES Haazim Riyaz 5th Blue Roll No. 27
  2. 2. WHAT IS AN INPUT DEVICE?  Any machine that feeds data into a computer is called an Input Device.  Any device that interacts to any system and allows you to enter the information on the computer.  An input device is a hardware or peripheral device used to send data to a computer.  An input device allows users to communicate and feed instructions and data to computers for processing, display, storage and/or transmission.
  3. 3. INPUT DEVICES:  MOUSE • A Mouse is a hand controlled pointing device which moves a pointer on a display. • A Mouse consists of an object held in one's hand, with one or more buttons. • A Mouse often also features other elements, such as touch surfaces and wheels. • The Mouse turns movements of the hand backward and forward, left and right into equivalent electronic signals that in turn are used to move the pointer.
  4. 4. INPUT DEVICES:  KEYBOARD • A keyboard is a typewriter-style device which uses buttons or keys to act as a mechanical lever or electronic switch. • A keyboard typically has characters engraved or printed on the keys and each press of a key typically corresponds to a single written symbol. • A keyboard is a panel of keys that operate a computer or typewriter.
  5. 5. INPUT DEVICES:  JOYSTICK • A Joystick is an input device consisting of a stick that pivots on a base and reports its angle or direction to the device it is controlling. • The electrical two-axis joystick was invented by C. B. Mirick. • The name "joystick" is believed to have been coined by a French pilot Robert Esnault-Pelterie.
  6. 6. WHAT IS AN OUTPUT DEVICE?  An output device is any piece of computer hardware equipment used to communicate the results of data processing carried out by an information processing system (such as a computer) which converts the electronically generated information into human-readable form.  An output device is any peripheral that receives data from a computer usually for display or projection.  An output device is a piece of hardware that is used to output data that has been previously entered into a computer or similar processing device.
  7. 7. OUTPUT DEVICES:  MONITOR • A Monitor is the piece of computer hardware that displays the video and graphics information generated by the computer. • A monitor usually comprises the display device, circuitry, casing, and power supply. • The display device in modern monitors is typically TFT-LCD or LED display, while older monitors used a CRT display.
  8. 8. OUTPUT DEVICES:  PRINTER • A Printer is a peripheral which prints a human readable representation of graphics or text on a paper. • The world's first computer printer was invented by Charles Babbage. • The two most common printer mechanisms are black and white laser printers and color inkjet printers.
  9. 9. OUTPUT DEVICES:  SPEAKER • A Speaker is a device which converts an electrical audio signal into a corresponding sound. • Speakers are typically housed in an enclosure which plays an important role in the quality of the sound. • The most widely used type of speaker today was invented in 1925 by Edward W. Kellogg and Chester W. Rice.
