Quality of Service

This refers to the assumption that data transmission rates, error rates, and other characteristics can be measured, improved, and to some degree, guaranteed in advance. Basically, QoS describes a collective measure of the level of service a provider delivers to its customers or subscribers. It is commonly used to compare against speed.

For example, Wi-Fi has the speed but not the QoS, and HomeRF has the QoS but not the speed. Service providers may guarantee subs a particular level of QoS defined in a service-level agreement.
