What's the difference...

A router routes incoming signals to different computers. It has it's own MAC address; hence it only needs to send one signal out, and then just process the incoming signals to each different computer.

 

A switch:

 

A mechanical or electronic device that directs the flow of electrical or optical signals from one side to the other. Switches with more than two ports, such as a LAN switch or PBX, are able to route traffic. See LAN switch, softswitch, PBX, data switch and transistor.

A router is used when you need to connect two or more networks (LANs, WANs, w/e). It also helps get the fastest connection between them by selecting the best path for the data packets to follow, especially when used with large networks. A switch is used for moving data around inside of a LAN, such as sharing an internet connection. The name describes what it does - it switches the connection to the appropriate machine, saving you network bandwidth. This is unlike a hub, which forwards all data to all nodes on the network.

As far as I was aware, a switch was basically something you would utilize if you didn't need the objects connected to it to have unique IP addresses when connecting to the internet. In the case of computers or an Xbox, a switch won't allow both to access the internet at the same time.

 

At least, that's been my experience with switches...

Getting a router, will generally render most firewalls not needed anyway, at least from external attacks. NAT takes care of most of hte issues of being open to the internet for attack. Only problem is stopping those that get through, via websites.. (IE stick to a software firewall only)
