I'm interested in this purely from personal interest, I'm not a student.
Can I express 1024 bytes of information travelling over cat5e as joules (or some measure that fits into energy of e=mc^2 )? How?
Would this be radically different if it were travelling through a CPU?
I have no practical application in mind, but ideally we could express the mass of a gigabyte, and contrast it with waste from latency of an hour long transfer, or something like that. I'm sure the medium it travels over dictates a lot of this.
