| NIC | the card that transforms data so that it can run throughout the network |
| Switch | a "hub" that can decide where to send its data |
| Router | makes decisions based on IP addresses, and can send information to various sources; uses IP addresses, layer III |
| Bridge | lets the "correct" information go through based on MAC addresses |
