Code is like a special language that people use to tell a computer what to do. It's a bit like a secret code that you can use to control the computer and give it instructions. It's like a set of instructions that the computer follows in order to carry out a task. For example, if you wanted to tell the computer to make a lemonade, you would have to write a program that tells it what ingredients it needs, how to mix them together, and when they are done.
