Comment on How does data sent over the internet know where to go?
LainTrain@lemmy.dbzer0.com 3 months agoIPs and packets are well and good and I do have a decent working knowledge of TCP/IP, but what physically is actually happening? Thanks for replying anyway!

Physically, at the physical / link layers, an integrated circuit is used that knows how to take data provided by the cpu and stick it into an Ethernet Packet and then make signals on the Ethernet (like RJ45) wires to communicate with the switch.
I would have to look up a data sheet on an Ethernet controller and read the IEEE 802 specs to know precisely what goes on.
