What is an expanded data processing cycle?

Answer 1

The data processing cycle is used anywhere data has to be input and processed in order to achieve a desired output. That output may be then used as input for additional processing, repeating the cycle. During processing, data is also stored for later use, whether to be processed along with new input or to provide input for other processes, thus creating new output.

The expanded cycle is the same, the only difference being that data has to be originated before being input, while the output has to be distributed. The originated data is known as the source document, which could be something as simple as an appointment booking form that you fill in. The data from that document is then input and processed (and stored), and the output is distributed in the form of report documents, which could be as simple as a letter telling you when your appointment is, a copy of which will be kept on file along with the source document. When you come to attend your appointment, your report document becomes the source document, which is then input and processed, and the output distributed, confirming your attendance for the appointment. During the appointment, new data is originated, thus starting the cycle all over again.

Answer 2

The (standard) data processing cycle has the following repeating loop:

1. Input
2. Processing <=> Storage
3. Output

The input stage is simply the point at which data is input while the processing stage refines the data in order to reach a desired output. the cycle then repeats. In some cases, feedback from the output may itself lead to the creation of new input. However, during processing, the processed data must be stored and may be subject to further processing and storage. Also, new input is often dependant upon the stored data from a previous input.

In the extended data processing cycle, there are two additional stages:

1. Origination
2. Input
3. Processing <=> Storage
4. Output
5. Distribution

The origination stage defines the point at which data is collected for input. The main data processing cycle is as before, however the output is then distributed in the form of report documents which may be used subsequent originations.

Answer 3

Expanded data processing is defined through three parts. They are origination, distribution, and storage. This is the process used by computers to save data during daily use.
