the primary reason for using a router is to efficiently direct packets (or data) from one network to another, thereby reducing excessive traffic in the whole network.
Bus topology as many nodes are connected to single link
no router is a network device using router only we can connect to different networks in a LAN so the answer is CPU.
Assuming you are using the OSI Modem a router sits on Layer 3: Network
A switch can be connected to the router using a crossover cable, to add more hosts to the network.

a router is a device used to connect two or more PC into a network using a LAN/Ethernet type cable. you can also have the wireless router to rid yourself of the cables when working on your laptop. In a home network your Internet connection will plug into the router and then several computers can connect to the Internet via the router.
The main advantage of using this is remote access on the network.
You have couple of choices. First is to connect your router to existing network using a cable. And then configure secured wireless network using your router settings. Second is to connect using Bridge configuration. You might run in problems with Bridge due to compatibility issues. You even will have change firmware to DD-WRT (if your router is compatible). Once you set Bridge then you go to router settings and configure secured wireless. And here you might run in problems too because you are basically extending non-secured network in a secured. A lot of routers will not allow you to do that.
You need to start with the basics,a backbone for your system.That's a router to distribute your broadband to all of the devices you intend to network.
Yes.
Did the change result in a 30% reduction in the time that it takes for data to travel from the router in building A to the router in building B
