What are communication between processes?

Processes are like teams working on different parts of a big project, and they need to talk to each other to make sure everything goes smoothly.

Imagine you're playing with your friends in the park. One friend is drawing a picture, another is counting how many leaves fall from the tree, and a third is passing around snacks. To work well together, they might shout messages across the field or use notes passed under the bench. That’s like communication between processes, each one doing its job, but also sending and receiving information to help everyone finish the task.

Sometimes, processes use a message board, like sticky notes on a wall, that's like sending messages in a shared place. Other times, they might call out to each other directly, like shouting across the park so only the person who needs it hears them.

These messages can be simple, like saying “I’m done with my part!” or more complicated, like giving instructions for what comes next. This helps everyone know when to move on or wait for their turn.
