what is a mos

mos - Computer Definition
(1) (Metal oxide semiconductor) See MOSFET.
(2) (Comment rating) Digital voice quality. This is a thematic metric provided entirely by people who listen to calls and get scores from 1 to 5. The sound quality of the dummy is mostly at a MOS level of 4 and above. MOS is the average of number for a given codec. Because MOS testing requires carefully prepared and measured test scenarios, the best way to perform a MOS test is through an external source. See codec. Objective Model E-Model is another rating system that provides quality measurement based on packet loss, jump and delay. The e-model reports the results as R-values. The following is an approximate relationship between MOS and E-Model quality scores. Thematic explanation MOS R Perfect 5.0 100 Excellent - almost not satisfied 4.5 90 Very good - Most satisfied 4.0 80 Good - Some are dissatisfied 3.6 70 Fair - Many are dissatisfied 3.1 60 Poor - Yes most dissatisfied 2.6 50 Poor - 1.0 0 Not recommended
