When I press a key on my keyboard, it will alter the flow of electrons in a wire connecting to send data to my computer. Let's say it sends the bits:
100000000100000000100000000100000000, which is a few letters encoded in binary and ASCII.
These electrons somehow move down the wire, to a chip, that detects where my data should go with transistors, or as I understand it, little switches that can be controlled with another wire. The chip will detect where my data is heading, and send it in the right direction.
So the question is, if I make a HTTP request from Europe to a server in USA, do some of electrons from my PC, in 200 ms the response takes, travel across the Atlantic ocean to USA and come back to me?
