Stages of Information Processing Cycle

               From the above, you can see that the Information Processing Cycle has four (4)
               stages. These are:
                          Input
                          Processing
                          Output
                          Storage





















                                                 Information Processing Cycle

               Input
               Input is the first stage of the cycle. Input is any data or instruction you enter into
               a computer. Data could be in the form of text, pictures, music, pictures, etc. this

               stage can be broken down into three (3) stages:
                      1.  Acquisition (Collection) of Data
                      2.  Entry of Data
                      3.  Validation of Data
               After the data has been acquired, it is entered into the system upon which the

               data is validated so that correct results are given at the end of the cycle. Input
               devices are used in this stage.

               Input Devices

               Input device is a device by which data is fed into the computer. It is any
               hardware device that sends data to a computer, allowing interaction and control
               the computer.
                          Examples of input device are; Keyboard, Mouse, Microphone,
                          Camera / Webcam, Scanner, Light Pen, Touchscreen (Finger), Stylus,
                          Digitizer, Barcode Code Reader, Trackball, Biometrics (Finger
