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! [?] 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?
