Rollover cable (also known as Cisco console cable or a Yost cable) is a type of null-modem cable that is often used to connect a computer terminal to a router's console port.
A console port uses a rollover cable and a special connector. The rollover cable is just a 8 wire cable in which pin 1 on one end goes to pin 8 on the other, pin 2 to pin 7, etc. The special connector is just a DB 9 (serial) female that has a RJ45 connector on the back where the rollover cable is inserted. It uses special wiring and tends to be specific to Cisco gear although there might be some exceptions. I suspect you might hear 'console cable' and it would refer to both the rollover cable and the connector as a whole.
