What are concurrent systems?

A concurrent system is like having several friends playing games at the same time in one room, everyone is doing their own thing but still interacting with each other.

Imagine you have a toy kitchen, and three of your friends are helping you cook. One friend is chopping vegetables, another is stirring the soup, and the third is setting the table. All of them are working together to get dinner ready, but they're not waiting for each other, they’re doing their tasks at the same time.

Concurrent systems work in a similar way. They have multiple parts that can do things at the same time, like your friends cooking together. This makes everything happen faster and more smoothly.

If you're used to taking turns with one friend, like passing a ball back and forth, then having several friends working at once feels like having more energy, more fun, and more action happening all around you. That's what concurrent systems do: they make sure everything happens together without waiting for each other.
