ELI5: Explain Like I'm 5

Shared resource

Imagine you and your friend want to play with a toy car, but there's only one car. This car is a shared resource, which means you and your friend have to figure out how to share it.

A shared resource is something that people need to use, but they have to take turns using it so everyone can have a chance. For example, if you're in a classroom and there's only one computer, everyone in the class needs to share it so they can take turns using it.

Sometimes sharing can be difficult, especially if people want to use the shared resource at the same time. This is why it's important to learn how to take turns and communicate with others so everyone can have a chance to use the shared resource.
