Quizplus · Accepted Answer

The three key concepts that ensure good quality of service from a computer system are reliability (the ability to perform consistently and predictably without failures), availability (the extent to which the system is operational and usable when needed), and serviceability (the ease with which the system can be repaired or maintained). Cost is not one of the key concepts, as cost can vary depending on the specifics of the system and does not directly impact the quality of service.
