How do i tell if im using a router of some kind :\?

router, computer, internet, connection to said internet via previously mentioned router.

Answer 1

A router is a hardware box. If you are using one, you will have a network cable which runs from your computer to the router. It will be some type of a "box" with ports for connecting multiple computers to it.

If you have only one computer, then you probably do not have a router. It is only used when you have multiple computers sharing a single Internet connection.
