The Data Processing Cycle

1. Data Processing cycle described all activities which are common to all dataprocessing systems from manual to electronic systems.

2. These activities can be grouped in four functional categories, viz., data input,data processing, data output and storage, constituting what is known as a data processing cycle.

3. The main aim of data processing cycle is to convert the data into meaningful
information.

The data processing cycle contains main four functions:
o Data input
o Data process
o Data storage
o Data output

DATA INPUT
o The term input refers to the activities required to record data.
o It’s a process to entered data in to computer system.
o So before we input any data, it is necessary to check or verify the data context.

DATA PROCESSING
o The term processing includes the activities like classifying, storing, calculating, comparing or summarising the data.
o The processing means to use techniques to convert the data into meaningful information.

DATA OUTPUT
o It’s a communication function which transmits the information to the outside world.
o After completed the process the data are converted into the meaningful in
o Sometimes the output also includes the decoding activity which converts the electronically generated information into human readable form.
