Exceptions and notes:
Consumer routers generally have one router port labeled [INTERNET] and four switch ports. For example: if you want to connect a PC to any of the ports NOT labeled [INTERNET], you'd use a straight-through cable in that case since they're technically switch ports.
On almost all modern devices, you don't have to think about this topic since the network cards can auto-detect whether to transmit/receive in crossover mode or not.
