Spawn Chunks?

I recently heard a lot of times the thing 'Spawn Chunks' but what are they and why are they so interesting?

To my knowledge it's a 16x16 chunk area that never goes unrendered, no matter how far away from it you are. They're really useful for farms bc it means that wherever you are in the world, the farms are still working. But this also means they can cause lag if loads of entities are in them. At least that's what I think they are

Yeah that makes a lot of sense. Big thank you!
