This is a CCNA question, the title pretty much says it all. What would happen if I connected a device with the wrong type of cable? Could the cable damage the device in some way?

Assuming we're talking about Ethernet connecting to Ethernet, without PoE (power over Ethernet) then no, connecting an Ethernet cable will not harm either device.

Connecting Ethernet to a modem port may harm one of the devices, but I forget which one. Connecting Ethernet with PoE to a device with the incorrect cable MAY harm the device NOT supplying power. There are likely several other combinations which could cause harm to either or both sides.
