"Pot" is short for potentiometer (changes the potential, as in voltage)
Attenuator is just that, something that reduces, or makes less (loud, for instance)
The result is the same in either case, and the terms don't necessarily describe a particular kind of physical device. Although pots are assumed to be continuous and attenuators intermittant.
The advantage of the stepped device is accuracy of each volume setting, as well as reduction of error between two channels, or two pieces of equipment at the same settings. However there are lots of conacts to get dirty or weak.
High quality wiper potentiometers, like the Alps or the TKD are as accurate as many stepped units, cheaper, and well suited for use in home audio where they won't be subjected to commercial conditions.
