Everyone has heard of Turbo Boost, as it is one of Apples most prominently displayed specifications about their computers, but I have no idea WHAT exactly it is. Does it mean they can be overclocked to get to that speed? Does it mean when it is plugged in and has enough battery it will run faster? Do I have to manually turn it on? How? What triggers it? I have nearly zero understanding of what it is and how it functions, and would really appreciate some insight.
