Data processing involves transforming raw data into meaningful information through a series of actions that collect, organize, and operate on data items. The ultimate goal is to convert raw data into useful information.

Data, in its raw form, serves as unprocessed input into a system, describing facts and figures that have not been categorized, related, or evaluated. Information, on the other hand, results from recording, organizing, classifying, and processing data into a meaningful and useful format, representing the output of a data processing system.

 

The qualities of good information include accuracy, timeliness, completeness, relevance, up-to-dateness, and cost-effectiveness. The stages of data processing include origination, preparation/sorting, input, processing, output, storage, and distribution.

 

Various methods or techniques of data processing include manual, mechanical, and electronic data processing. Electronic data processing involves the use of computers, which possess characteristics such as high speed, large storage volume, versatility, diligence, and automation.

 

A computer comprises input devices (e.g., keyboards, terminals), a central processing unit (with a control unit, arithmetic and logic unit, and internal memory/storage), output devices (e.g., printers, visual display units), and storage devices (e.g., diskettes, magnetic tapes).

 

In commerce, computers find applications in finance, including E-Commerce, E-Banking (such as online banking), E-Business, E-Payment, and E-Government. These applications leverage the speed, storage capacity, versatility, and automation capabilities of computers to enhance various aspects of commercial operations.
