Runtime system

Okay kiddo, imagine you have a toy robot that can do lots of things such as walk, talk, and move its arms. But if you want it to do something specific at a certain time, you need to give it instructions. Think of these instructions like a recipe that tells the robot what to do step by step.

Now imagine your computer is like a big toy factory that makes lots of robots. Each robot has its own set of instructions or recipe that tells it what to do. But who or what is going to make sure that the robots follow their recipes properly?

This is where the "runtime system" comes in. It's like the mommy robot that helps take care of all the other robots. It's responsible for making sure each robot follows its recipe correctly and behaves properly.

But how does the runtime system do this? It has two main jobs:

1. Managing the resources: Just like you need different ingredients and tools to make different types of food, the robots need different resources (like memory, processing power, and input/output devices) to perform different tasks. The runtime system makes sure the robots have the resources they need, and that they use them in a fair and efficient way.

2. Translating the code: Remember the robot's recipe? Well, it's written in a special language that only robots can understand. But your computer doesn't speak that language! So the runtime system has to translate the recipe into a language that the computer can read and execute.

Overall, the runtime system is like the boss that manages and coordinates all the different robots in the factory. Without it, the robots would be lost and unable to do their jobs properly.
