Chapter 3 - Information (Data) Processing Cycle

               In this chapter we’ll define Information (Data) Processing Cycle, describe the

               various stages of the cycle (input, process, output, storage and distribution) and
               finally, name the devices used in all the stages of the cycle.


               What is Information Processing Cycle?

               Information Processing Cycle is a sequence of events that describe how data is
               transformed or changed into information. It refers to the series of identifiable
               steps the computer goes through to accept and process data into information,
               store the information for future use, and/or share it with others. It is likened to

               the milling of corn into corn dough as shown in the picture below:



























                                          Grinding [Milling] of Corn into Corn Dough


                 Grinding of Corn into Dough Picture – The Corn (Data) is poured into a
               cone shaped container on top while the man (User) seated by the Grinding
               Machine gradually feeds the grinder (Processor) with the grains (Input). The
               Dough (Output) will be received by a container (Storage) after it has been
               processed.

               In short, the corn (Input) is grinded (Processed) into Dough (Output) and kept
               in a container (Storage). Remember that, all these were done with the help of an
               operator (User).
