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).
