Lava is the extrusive equivalent of magma. Magma (from Greek Î¼Î¬Î³Î¼Î±, thick unguent) is a mixture of molten or semi-molten rock, volatiles and solids that is found beneath the surface of the Earth, and is expected to exist on other terrestrial planets. Besides molten rock, magma may also contain suspended crystals, dissolved gas and sometimes gas bubbles.
Mean opinion score. Mean opinion score (MOS) is a measure used in the domain of Quality of Experience and telecommunications engineering, representing overall quality of a stimulus or system. It is the arithmetic mean over all individual âvalues on a predefined scale that a subject assigns to his opinion of the performance of a system qualityâ.
MOS (mean opinion score) is a voice call quality metric. It is used by the VoIP industry to put a number on voice quality. In reality, this number is a subjective 'opinion' rating of call quality given by someone who was just on a voice call. Obviously, with PingPlotter we don't have someone doing a voice call on your line all the time, and then giving an opinion number.
