The Computer Is a Giant Copy Machine
The electronic world we live in is really a giant machine copying bits from one place to another without error. When turned on, every device with a computer chip copies signals internally 24/7. We read something on the screen because it was copied from storage to RAM and then to the screen. The contents of RAM are copied to the network, and the other end copies the bits into a computer's RAM. The electronic world is a giant digital copy machine!
