Information processing is the reception, storage, conversion, transmission and release of information. With the continuous development of computer science, computers have developed from early computing tools based on "calculation" to tools based on information processing, integrating calculation and information processing, which are inseparable from people's work, study and life.
The process of computer information processing is actually the same as that of human information processing. People also get information through sensory organs, transmit and store information through the brain and nervous system, and finally release information through words, actions or other forms.

Three stages of information processing:
1. Manual processing cycle
The manual processing period is to collect information manually, record and store information in words, process information with experience and simple manual operation, and transmit information with portable storage media.
2. Mechanical information processing cycle
With the development of science and technology and people's pursuit of improving information processing means, mechanical and electronic processing tools, such as abacus, cashier and hand-cranked computer, have gradually appeared, which has lightened the burden of calculators to some extent.
3. Computer processing cycle
With the improvement of computer system in processing ability, storage ability, printing ability and communication ability, especially the development of computer software technology, it is more and more convenient to use computers. The breakthrough of microelectronics technology has made microcomputers increasingly commercialized, thus creating excellent material conditions for the application of computers in management.
