Data processing refers to the process of collecting and manipulating raw data to yield useful information. Data processing is also the conversion of raw data into machine-readable form and its subsequent processing by a computer.
Data processing converts the otherwise unusable data into a useful form. It involves data storage, organization, modification and final presentation of the desired information. Processed data comes in the form of reports, diagrams and tables. In computing, processed data comes in audio, video, graphic, diagrammatic, text and numeric forms.
