Diagram of the IPO cycle.
The sequence a computer follows to turn data into a useful result.
The hook linking brain functions to the IPO cycle.
Think about how you solve a simple math problem in school. First, you see the numbers on the board with your eyes. This information you take in is your Input.
Define Data, Instructions, Input, Process, and Output.
The Input is whatever we give to the computer. It consists of two parts:
Practice identifying I, P, and O in real-world examples.
Let us look at a real-world example of the IPO cycle when making juice. The raw fruits act as the input, and the serves as the processing phase. Finally, the delicious juice you drink is the final . A computer works exactly the same way when we want it to add two numbers. Typing '2+2' into the keyboard is the step. The computer then uses its brain, the , to perform the addition during the process phase. The result of this calculation is the output, which is seen as the .
