"Then I should think of it like paper, and if it's supposed to go somewhere else, then the machines do the work of a mailpony and send it to where it's supposed to go?" Putting a hoof to her chin, she turned that around in her head till it made some sort of sense. "Okay, I can get that! So I guess these 'radio' waves are like a pegasus, they fly through the air, and if it goes through 'cables' it's like an earth pony carrying them on the ground?"
