Hello. This might sound a silly question but I'm confused. I have been doing research but can not find any information on this. Do Macs have NIC cards that allow them to connect to the internet, or is that just for PCs? If they don't have NIC cards, what else is it known as? When I go on the Apple website, on the diagrams it just says "gigabit ethernet" and nothing else about ethernet. It says something on "Tech Specs" but it is not really that detailed. The reason why this is in Mac Mini is because that is what I am studying. However this generally counts for any Macs. Thanks!
