Okay, I’ve been watching lots of YouTube videos about switches and I’ve just made myself more confused. Managed versus unmanaged seems to be having a GUI versus not having a GUI, but why would anyone want a GUI on a switch? Shouldn’t your router do that? Also, a switch is like a tube station for local traffic, essentially an extension lead, so why do some have fans?
I feel like you would benefit from revisiting the OSI model

Switches can have many different purposes, and can act as a router or not. This series of videos covers the OSI model, and provides some information on how many layers of the OSI model an individual switch can capture.
Thank you
