-The EVA principle in computer science describes a basic process that almost every computer programme and every electronic data processing system goes through. EVA stands for "input, processing, output" and summarises the three essential steps of data processing.+The IPO principle in computer science describes a basic process that almost every computer programme and every electronic data processing system goes through. IPO stands for "input, processing, output" and summarises the three essential steps of data processing.

 All data processing begins with the input of information or data. In computer science, input refers to the transfer of data or commands from a user, a sensor or another system to the computer. All data processing begins with the input of information or data. In computer science, input refers to the transfer of data or commands from a user, a sensor or another system to the computer.

 **Example:** You type the numbers "2" and "3" into a calculator to perform a calculation. These numbers are the input data. **Example:** You type the numbers "2" and "3" into a calculator to perform a calculation. These numbers are the input data.
  
-==== E(V)A - The processing ====+==== I(P)O - Processing ====
 Once the computer has received the input data, processing takes place. The computer works with the help of a programme that determines what is to be done with the input data. This step is the central point of data processing. Once the computer has received the input data, processing takes place.

 **Example:** You enter a "+" on the calculator and press "=". The calculator now processes the input "2 + 3" and carries out the calculation. **Example:** You enter a "+" on the calculator and press "=". The calculator now processes the input "2 + 3" and carries out the calculation.

 At the end is the output of the processed data. The computer either displays the result on a screen, prints it on paper or passes it on in another form, e.g. as a signal to another device. At the end is the output of the processed data. The computer either displays the result on a screen, prints it on paper or passes it on in another form, e.g. as a signal to another device.
Zeile 51: Zeile 51:
 **Example:** After the calculator has processed "2 + 3", it shows the result "5" on the display. This is the output. **Example:** After the calculator has processed "2 + 3", it shows the result "5" on the display. This is the output.
  
-===== The EVA principle in practice =====+===== The IPO principle in practice =====
  
 We encounter the EVA principle constantly in everyday use, even if we often don't realise it. Every time we use a computer or electronic device, this process is running in the background. A particularly tangible example is an ATM. We encounter the EVA principle constantly in everyday use, even if we often don't realise it.
