Definition - What does Zettaflop mean?
A zettaflop (ZFlop) is a unit of measurement for computer processing power. It refers to the floating point operations per second (FLOPS) capacity of a processor, where one ZFlop represents 1021 FLOPS.
Techopedia explains Zettaflop
Computer design professionals and analysts believe that to reach zettaflop computation in computers/processors, on-chip photonic communication and memristor memory techniques must be implemented within their design. Moreover, to operate, zettaflop processors/computers will require approximately 400 watts of power.
