Input, process, output, storage
You speak into a tablet. Words appear on the screen. Which part is the input?

Your voice is the input, the thing that goes in.
Fruit and curd go into a blender. You press the button. A smoothie comes out. A computer works the same way.
Step 1 of 4
- Fruit and curd go in. That's input.
- The blades mix it. That's the process.
- A smoothie pours out. That's the output.
- Some goes in the fridge. That's storage.
A computer takes input, processes it, gives output and can store it.
- Input — what goes in: a tap, a word, a photo.
- Process — the computer works on it, step by step.
- Output — what comes out: words, a sound, a picture.
- Storage — where a copy is kept for later.
These four parts, in order, are the loop.
