Those cables have the _exact same_ function, one for serial, the other for ethernet. And if I may point something else out, the phrase "connects two Ethernet ports" is non-informative. Like if you would have used "two serial ports" in the second. Also consider that for ethernet all 'puters are comparable to DTEs from the serial-port case, with the modems, hubs and switches taking the place of DCEs. Maybe that makes it easier to see how both cables are effectivily the same.
