How do machines affect work?

What is true about machines in the real world?
In the real world, machines are never 100% efficient. There is always loss of energy, usually due to friction. By contrast, in physics problems, an "ideal machine" is a hypothetical device which is perfectly efficient. The assumption of perfect efficiency allows the problem to focus on the fundamental mechanical principles.
The disadvantages of friction?
Losses due to friction mean that in a closed system there is never 100% transfer of energy and therefore no such thing as Perpetual Motion machines (although some get close).
