A couple of these answers are wrong. “Like” devices require a crossover cable, so computer-computer is a crossover, switches and hubs are similar devices so switch-hub should be a crossover. Router-switch are dissimilar so that would be a straight-thru cable. Computer-switch would also be a straight-thru. Console ports can vary, but typically it’s a DB9 or RJ45, not RS-232. They are considered “roll-over” cables. So the Console port should be a rollover.
