How Do Computers Know What to Calculate?

Computers use instructions to know what to calculate, just like you follow a recipe to make cookies.

Imagine your computer is like a robot chef who doesn’t know how to cook unless you tell it exactly what to do. You write down the steps, and it follows them one by one.

Inside a computer, everything is made of tiny switches that can be either on or off, like a light switch in your room. These switches are called bits, and they help computers understand instructions.

When you tell a computer to add two numbers, it uses these tiny switches to do the math. It’s like counting with lights: if one light is on (which means 1) and another is also on, the computer knows that equals 2.

People write codes, special instructions made up of letters and symbols, so computers can understand what they need to do. These codes are like secret messages that tell the robot chef how to bake a cake or solve a puzzle.

So when you play a game or type a message, your computer is just following its favorite recipe, step by step!
