The Internet: A Global Note-Passing Game

The internet is literally just a global game of passing notes in class at light speed.

It isn't magic, it’s the OSI model. Think of every click as sending a letter. You write the message

at the Application layer, then you pick your shipping method. TCP is the strict

courier making sure every single packet arrives perfectly in order, while UDP is the

chaotic mailman who just throws the box at your porch and runs. Routers act like

international post offices reading IP addresses, while switches are the local delivery

guys checking MAC addresses. It takes seven layers of complex translation just to send a meme,

but it happens so fast you never even notice the work.
