The details processing cycle, in the context of computers and also computer processing, has 4 stages: input, processing, output and storage (IPOS). However, at part levels in ~ a computer, some processing tools actually just use 3 of this stages -- input, processing and output -- there is no the need to store data. Every of this stages plays critical role in the collection, analysis and circulation actions performed by a computer system.

Data must get in a system before it can be processed into either save data or information output. The input stage of IPOS gives the way and mechanisms through which data start the IPOS model. Some experts think the input procedure itself could be split into as many as three stages: collection, preparation and also input. However, the general view that the input stage is the data is input into a system using some kind of an intake device.

An input machine is maybe to collection data in ~ its resource or suggest of measurement. The resource of data gone into into the system by a human is v a keyboard, microphone or perhaps also the motion of eye or an additional body part. Other develops of entry devices, such as thermometers, sensors and clocks, additionally meet the general meaning of input devices. The input stage of IPOS could also be described as the encoding stage.


Once data start the IPOS model, the is processed into either save on computer data or information. The processing agent is commonly some form of software or firmware, through a details action taken on a particular type of data. In a portable or desktop computer computer, the is usual for the handling agent come be energetic even prior to the data enters. In fact, the is also common for the handling software to inquiry data and also guide its intake process.

Processing can selection from relatively small and straightforward to very big and complex. Regardless, the sole function of the processing stage is to convert the life input data right into a type that can be stored for later on use or provide information calculation for further processing or interpretation.


Output handling in IPOS sends details to a screen screen, a printer, a plotter, a speaker or part other medium that human being senses can interpret. However, the output stage can store the data in a brand-new format or change the handle data into an entry to an additional IPOS module together well. For many users, output method either a display on a monitor screen or a printed paper or graphic. Calculation can additionally mean data, info or coding.

The storage phase of IPOS can occur straight from or come the processing or the output stages. The warehouse stage can serve together a pseudo-input or pseudo-output stage for the processing stage. The processing stage might need to keep data for later on use or recall formerly stored data for processing new data from the intake stage. The output stage may store handle data as details for display screen by one more IPOS module as soon as needed. The storage phase does not only store data or info on a fixed storage medium, such together a hard disk, yet can additionally store data and information on removable media, such as a flash drive, CD-ROM or DVD.
