Transcript

  • 1. Computer software system input process storage output
  • 2. INPUT DEVICES
    • An input device is any peripheral (piece of computer hardware equipment)used to provide data and control signals to an information processing system (such as a computer ). Input and output devices make up the hardware interface between a computer as a scanner or 6DOF controller.
    • Keyboards
    • Pointing devices
    • Imaging and Video input devices
    • Audio input devices
  • 3. keyboards
    • A keyboard is a human interface device which is represented as a layout of buttons. Each button, or key, can be used to either input a linguistic character to a computer, or to call upon a particular function of the computer. Traditional keyboards use spring-based buttons, though newer variations employ virtual keys , or even projected keyboards .

  • 4. Pointing Devices
    • A pointing device is any human interface device that allows a user to input spatial data to a computer. In the case of mice and touch screens, this is usually achieved by detecting movement across a physical surface. Analog devices, such as 3D mice, joysticks , or pointing sticks , function by reporting their angle of deflection. Movements of the pointing device are echoed on the screen by movements of the cursor , creating a simple, intuitive way to navigate a computer's GUI .

  • 5. IMAGING and VIDEO input devices
    • Video input devices are used to digitize images or video from the outside world into the computer. The information can be stored in a multitude of formats depending on the user's requirement.
    Back to input
  • 6. Audio INPUT DEVICES
    • In the fashion of video devices, audio devices are used to either capture or create sound. In some cases, an audio output device can be used as an input device, in order to capture produced sound .
    Back to input
  • 7. PROCESS (COMPUTER SOFTWARE SYSTEMS)
    • a process is an instance of a computer program , consisting of one or more threads , that is being sequentially executed [1] by a computer system that has the ability to run several computer programs concurrently .
  • 8. OUTPUT DEVICES
    • 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 ) to the outside world.
  • 9. STORAGE DEVICES
    • A storage device may hold information, process information, or both. A device that only holds information is a recording medium . Devices that process information (data storage equipment) may either access a separate portable (removable) recording medium or a permanent component to store and retrieve information.
