Interface description language

Imagine you have a toy car that needs different kinds of batteries to work. Some need two AA batteries and some need three AAA batteries. But how do you know which one needs which type of battery? You look at the bottom of the car and it has pictures and descriptions that tell you how many and what type of batteries it needs.

Similarly, computers need to communicate with each other but they speak different languages. One computer might be able to speak in Java while the other can only understand Python. So, just like the toy car, they need descriptions that tell them how to communicate with each other. That's where Interface Description Language (IDL) comes in handy.

IDL is like a dictionary that computers use to talk to each other. It tells them what kind of information they can send and receive and how it should be formatted. It helps computers understand each other's languages and work together smoothly.

So, just like how you read the bottom of your toy car to understand what batteries it needs, computers use IDL to understand each other's language and communicate properly.
