Understanding Networking: The Digital Neighborhood

Your computer is basically living in a massive, chaotic neighborhood. That is literally

all networking is. The cables are just the roads, and your data is the traffic trying

to get home. Here is the wild part: every device has a permanent birth name called

a MAC address, but its IP address is just a temporary house number that changes whenever

it moves. When the internet dies, we use the seven-layer OSI model to hunt

down the issue, checking everything from the physical wire to the app itself.

Master these traffic rules, or you are just staring at blinking lights.
