I think it's just a measurement. Like this computer has a 3 GHz processor. So it makes so many decisions per second.
Soon a processor will have the same processing speed as the human brain (which is pretty fast considering sight, spacial awareness, muscle movements, involuntary body functions, thought, speech, memory etc).
Possibly in 30 years a computer could process every decision a human brain makes over the period of an average lifetime in an hour.
It's also been thought that one day a computer will be able to process as much as all the decisions every human brain has ever made within a small period of time.
I have no idea why we'd need this. But MS Access will load very fast.
These guys are involved with pushing the limit of processing power. Also a customer.
