If you check out the "task manager" or "system monitor" (or similar tools) in your operating system, you will be able to see many of those processes running.

And, for example, you will probably see that there are multiple processes running the same browser program (Firefox, Chrome, Edge, etc). They normally run one process per tab, plus some other extra processes.

But it's not possible to have a running container without **at least one running process**. If the main process stops, the container stops.
