How is it that you can "program" a piece of metal, such as a chip or board? I wish I knew! Is there a series of lines and dashes that do that? I'm completely baffled as to how someone gets a piece of metal to read another piece of metal and makes it into a working machine! :frown: [?] What is the basic mechanism at the base of all this that drives a computer or any other form of computer-based technology? What is the process that brings this all to life?

It's all thanks to the glories of quantum mechanics in play in a semiconductor, allowing you to make what is essentially a load of switches work together.
 
But it's important to realize that the "switches" mentioned are not physical or mechanical switches in the normal sense. They are peaks of magnetic fields in the metal. There's a good explanation at this site.

I understand that by 2010, a one-petabyte (1,000 terrabytes, or 1,000,000 Gig; enough disk-space to store the entire Library of Congress fifty times!) disk should be created, using carbon nanotubes.
