Hey kiddo, have you ever played with Legos and made a building instead of just stacking them up? Well, think of simple data format like that.
Simple data format is a way of organizing information, just like Legos help organize your building pieces.
Imagine you have a big pile of Legos, and you need to build a car. You wouldn't just throw all the pieces together and hope it works, would you? No way! You would organize the pieces first by color and size, so that you can easily find the pieces you need to build your car.
Simple data format does the same thing with information. It helps organize different pieces of information into a structured format so that it can be easily accessed and understood by a computer program.
So when you ask your computer to open a file, the simple data format tells the computer how to read and organize the information in that file. Just like how the organized Legos can help you build a better, sturdier car!
