What are examples IPO cycle?

IPO cycle stands for Input-Process-Output cycle

For example, if you want to make a copy of an important paper, you first scan the paper (inputting the data), make adjustments if you want to (processing the data), and the print it (outputting the data).

Here, the scanner is the input unit through which you feed the data to the computer.

The CPU is the processing unit which applies the changes you make to the data, that is, it processes the data.

The printer is the output unit through which you obtain the result of the data you earlier fed to the computer.
