Is it possible to interface with the operating system of simple devices, for example, a toaster?

I have some programming experience, but certainly nothing of this level. I believe devices like this often have Linux operating systems. Can anyone shed some light? I would be grateful.

Something like a toaster probably wouldn't have an operating system. Something like a smart fridge or a TV with chromecast-like features would.

This is usually called "rooting" a device similar to when it's used towards phones. You gain access to the OS and can do whatever you want with it.

A toaster usually has no software, and you will see this is a common theme for most if not all appliances.
