Imagine a computer like a robot with a list of instructions. It reads one line at a time and follows it, just like you would if someone told you what to do next. If the instruction says jump, it jumps; if it says wait, it waits. That’s how computers know what to do next, they follow a simple, step-by-step plan.
The Robot's Instructions
A computer uses something called code to tell it what to do. Code is like a recipe that the computer reads from top to bottom. Each line in the code is a small instruction, such as add 2 and 3 or print Hello World. By following these instructions one by one, the computer can do amazing things, even play your favorite video game.
Examples
- A computer follows instructions like a robot following a list of steps.
- When you press a button on your phone, it knows what to do because the code inside tells it so.
- Like reading a recipe one line at a time, that’s how a computer works.
