Example Citation:
Since the first ENIAC computer, which just celebrated its 50th anniversary, crunched numbers using 18,000 vacuum tubes, the efficiency of information technology has increased by 32 orders of magnitude. That’s about 100 nontillion times — 100,000,000,000,000,000,000,000,000,000,000. Analysts say one modern work station has the same power as all of the computers that existed in the 1960s.
