Did you know?
Efficiency is very often confused with effectiveness. In general, efficiency is a measurable concept, quantitatively determined by the ratio of useful output to total useful input. Effectiveness is the simpler concept of being able to achieve a desired result, which can be expressed quantitatively but does not usually require more complicated mathematics than addition. Efficiency can often be expressed as a percentage of the result that could ideally be expected, for example if no energ… WebTransfer efficiency varies between levels and is not exactly 10 % 10\% 1 0 % 10, percent, but we can see that it's in the ballpark by doing a few calculations.
