Terminal node controller

Okay kiddo, a terminal node controller, or TNC for short, is like a translator that helps computers talk to each other when they are far away. Think of it like a walkie-talkie, but for computers. It helps them send messages to each other even if they are really far apart. The TNC controls how the message is sent and makes sure it gets to the right place. This is really important for people who use radios to talk to each other, like pilots, firefighters, and hikers. The TNC helps them stay connected and safe, even when they are far away from each other.
