What is "Zettatechnology"?

Nanotechnology Introduction
"Nanotechnology is also known as ‘Molecular manufacturing’ or molecular construction. Each article processed using nanotechnology has certain characteristic features by itself. Nanotechnology deals with these properties taking one molecule of the material at a time and building them to the desired object" ... "Technically speaking nanotechnology deals with building molecule by molecule one of the following – a) incredibly small and highly advanced processors and chips of computers and machines or b) ordinary materials using highly advanced and extremely machines which are usually known as assemblers or fabricators.
Nanotechnology uses the molecular properties of an object to build a desired structure" http://www.nanotechnology-2007.com/nanotechnology-introduction.html

"Since the emphasis is on large-scale atomic precision, it is natural to seek a name that refers not to the nanometer scale of the parts, but to the number of distinct, designed parts in a macroscopic product, typically on the rough order of a sextillion (1021). Since the prefix "zetta-" denotes this number, the term "zettatechnology" naturally describes molecular manufacturing and its products (for comparison, the total world output of transistors has not yet reached one sextillion). One can thus speak of advanced nanotechnologies as eventually enabling zettatechnology,..." http://www.foresight.org/nanodot/?p=1349
