### What is a Process { #what-is-a-process }

The word **process** is normally used in a more specific way, only referring to the thing that is running in the operating system (like in the last point above):

This is just standard Python, it's called a "type alias", it's actually not specific to **FastAPI**.

But because **FastAPI** is based on the Python standards, including `Annotated`, you can use this trick in your code. 😎
