Hey there!
Just to be corny, what does a spider use to navigate the internet? The World Wide Web! Did you catch that? Hopefully you did...
Anyway, enough with my jokes, here's your answer.
Transmitting information through computers are cheap and fast because of multiple things. The first reason is because they don't require a deliverer or shipping. They can literally be sent from anywhere and be delivered within 10 seconds-5 minutes, way faster than any mailman or delivery. How does it move that fast? Smaller files tend to move quicker among the invisible online delivery lines, most commonly known as cell towers. To get online info from your phone/computer to someone else's device, the file bounces from tower to tower to finally reach the destination.
I'm always open to any question or comment!
God Bless!
