The data processing process is roughly divided into three stages: data preparation, processing and output. During the data preparation phase, data is input offline to punched cards, punched paper tape, tape, or disk. This stage can also be called the data entry stage.

After the data is entered, the data must be processed by the computer. For this purpose, the user must prepare a program in advance and input the program into the computer. The computer processes the data according to the instructions and requirements of the program. The so-called processing refers to one or a combination of several of the above eight aspects of work. The final output is various text and numerical tables and reports.
