The terms "anode* and cathode have their own problems. The cathode is that terminal of a device where positive current emanates. The (+) terminal of a batter is normally a cathode, but when the battery is being charged, it becomes an anode.
The terms anode and cathode should be burned. We don't use them much in modern electronics. E.g. we don't say that the positive power pins of a CPU are anodes, or that ground pins are cathodes.
