employed separately
Allows human thought to be translated into
efficient processing of large amounts of data

 The
Four Stages of Data Processing

Input: Data is collected and entered into
computer.

Data processing: Data is manipulated into
information using mathematical, statistical, and
other tools.

Output: Information is displayed or presented.

Storage: Data and information are maintained for
later use.
