Yes indeed!  It brings to mind a paper I read a couple of years ago, J. F.
(2011). A material history of bits. *Journal of the American Society for
Information Science and Technology*, *62*(6), 1042-1057.  Underneath the
abstractions there are physical phenomena - such as magnetic domains on a
tape.  Cheers -- Ian
