Information Processing in Computer

What does Information Processing mean?

Information processing refers to the manipulation of digitized information by computers and other digital electronic equipment, known collectively as information technology (IT).

Information processing systems include business software, operating systems, computers, networks and mainframes. Whenever data needs to be transferred or operated upon in some way, this is referred to as information processing.

A computer information processor processes information to produce understandable results. The processing may include the acquisition, recording, assembly, retrieval or dissemination of information. For example, in printing a text file, an information processor works to translate and format the digital information for printed form.

To understand how a computer functions you must understand the information processing cycle.

What is the information processing cycle? The sequence of events in processing information, which includes (1) input, (2) processing, (3) storage and (4) output. These processes work together and repeat over and over. 

  1. Input—entering data into the computer.

  2. Processing—performing operations on the data.

  3. Storage—saving data, programs, or output for future use.

  4. Output—presenting the results.
