I understand that a hub is more like a party line, where all devices hear and read data before sending it to next port, and a switch is advanced hub. But, what is a router. I know what a wireless router is, but they say a router is more advanced than a switch. Can you buy a non-wireless router?
Also, can you connect 2 switches together? So, Modem-----to Switch----to Switch----Computer
And both switches have other devices connected?
