	An '''Ethernet Switch''' works much like a Hub, but it is more selective of where to send received packets of data. Instead of transmitting the data to all connected NICs, a Switch reads the destination address and forwards the packet to that NIC only. This is accomplished using a routing table in the switch which keeps track of the connected IP addresses and the associated MAC addresses of the NICs.

-	an '''Ethernet Router'''	+	an '''Ethernet Router''' is very similar to a Switch, with added functionality. Like a Switch, it reads the destination address of every incoming data packet and transmits it only to that NIC. Also like a Switch, a Router uses a routing table to accomplish this selective forwarding, storing the IP address and associated MAC address for each NIC.
		+
		+	Routers also have configuration software on them, allowing a user to configure the router settings remotely. Typically, a Router also has firewall software installed on it, which can also be configured remotely.
		+
		+	===Advantages===
		+	* Low probability of data collisions due to data packets only being transmitted to a single NIC.
		+	* Collisions at one NIC does not affect other NICs
		+	* Remote configuration makes network administration easier
		+	* Firewall software helps protect the network from outside threats, provided the router is the only link between the local network and external networks.
		+
		+	===Disadvantages===
		+	* More configuration required
		+	* Firewall can cause problems in the network if configured incorrectly
		+	* Attackers can attempt to gain access to the router, and if successful, take control of the network policies.
