  3. Input and Output Devices

  4. Introduction Do you ever wonder how information gets into your computer and how comes out in a form you can use ? It is possible with the help of input and output devices.

  5. Input Devices Definition : “An electromechanical device that can be used to enter data and instructions into a computer.”

  6. Keyboard • “A keyboard is a human interface device which is represented as a layout of button or keys.” • It has some Features as • Typewriter keyboard with numeric keypad • Special purpose keys • Toggle and combination keys

  7. Pointing Devices Definition : “An input device used to control a pointer on the screen.” Mouse: “mouse can be used to Control and manipulate cursor movement on monitor.” Types of Mouse : i) Mechanical ii) Optical iii) Cordless or wireless

  8. Some pointing devices are • Trackball • Pointing Stick • Joystick • Touch Pad • Touch Screen • Light Pen

  9. Optical Input Devices “optical input devices that uses light as a source of input. They eliminate the need for manual entry of data, thus accuracy increases. Scanner: “scanners can be used to copy the image or text on paper into a digital format that can be used by the computer.”

  10. Other Optical Input Devices are: • Optical scanners • Flatbed • Portable • Bar code readers: • “A Barcode Reader is an electronic device which is used for reading printed barcodes. This device directs a light beam across the bar code while it measures the amount of light which is reflected back. “

  11. Character and mark recognition devices • Scanners that recognize special characters & marks • Magnetic ink character recognition (MICR) • Optical-character recognition (OCR) • Optical-mark recognition (OMR)

  12. Audio Input Devices Definition : “Audio input devices record the analog sound and convert it into digital form for further processing.” Some Audio input devices are : Voice recognition microphone Musical Instrument Digital Interface

  13. Video Input Definition : “ video input devices that can be used to entering full motion recording into a computer .“ Some video input devices are digital camera webcam video capture card

  14. Output Devices Definition “Output devices can be used to receive information from the computer “ The output can be in two forms: Soft copy Hard copy

  15. Monitor Definition “A monitor is a peripheral device which displays computer output on a screen . Screen output is referred to as soft copy” • Features • Resolution-pixels • Dot pitch • Refresh rat • Size • Types of monitors • Cathode Ray Tube (CRT) • Liquid crystal Display (LCD)

  16. Printer Definition “A printer is a peripheral device that produces a physical copy or hard copy of the computer’s output.” Types of Printer : Impact Printers • Dot Matrix Printer • Daisy Wheel Printer Non Impact Printers • Laser Printer • Ink-Jet Printer • Thermal Printer

  17. Plotter Definition “A plotter is an output device that is used to produce high quality graphics in a variety of colors.” Types of Plotter • Flatbed Plotter • Drum plotter

  18. Audio output Devices Definition “Audio Output Devices can be used to translates audio information from the computer into sounds that people can understand.” • Common audio output devices • Speakers • Headphones

  19. Projector Definition “Projector can be used to displays computer information on big screen so that many will able to see the show.”

  20. Computer Output Microfilm (COM) • This technology is used to record computer output as a microscopic film images. • Information is recorded on a roll of film. • COM devices are used applications where there are large volumes of data.

  21. Combination Input and Output Devices Many devices combine input and output capabilities • Fax machines • Multifunction devices • Internet telephones • known as Telephony • and Voice-over IP (VoIP) • Terminals

  22. Fax machines Definition : “A fax machine refers to a device or equipment that does telephonic transmission of scanned material. It scans the original document and converts it into a bitmap. It then uses electronic signals to send the document to another recipient. “

  23. Terminals • An input and output device • Connects to a mainframe or server • Types of terminals • Dumb terminal • Intelligent terminal • Network terminal • Internet terminal
