What do the Hash terms mean, really?
Blockchain and Bitcoin are not very old, but the increase in processing speed is incredible. CPU’s only a couple of years ago could hash at 1,000,000 hashes/sec.
ASIC speeds are now in the PetaHash range, about a billion times faster.
Here is the terminology, defined:K equals a thousand (units)M equals a million, which is a thousand times thousandG (Giga) equals a thousand times of the M. (a Billion)T (Tera) equals a thousand times of the G (a Thousand Billion)P (Peta) equals 1000T, (so 1 Million Billion Hashes/sec)For the exact number, 1 Peta = 1,000,000,000,000,000 units.
