Every Networking Technology Explained In 13 Minutes!

Ethernet, Wi-Fi, NFC, VPN, VLAN, LoRaWAN — networking comes with a ridiculous number of names, but they're all solving the same basic problem: getting devices to communicate. The difference is how they do it, how far they reach, and what they give up to get there. Thirteen networking technologies from a cable that shows up at 7:55 when Wi-Fi says "I'll be there around eight," to pulses of light carrying data through glass thinner than a hair, to a tiny sensor in a field that transmits once every few minutes and runs for years on a single battery. A radio wave that connects your headphones but occasionally pretends not to see them. A tap so fast you don't realize two devices just talked. A tunnel that protects your traffic but isn't the invisibility cloak the ads promise. And a system that turns your electrical wiring into a network cable — with results that depend entirely on what's behind the wall. -------------------------------------------------------------------- #Networking #TechExplained #WiFi #Internet
