****I recently started my coding journey with Go. If you’re a beginner looking for a language that is simple yet incredibly powerful, I can’t recommend Go enough. While building my first Go HTTP web server, I hit a point of curiosity. I learned that a server must "listen" on a specific port number, but I kept seeing 8080 in every tutorial instead of the standard 80. I did some digging, and here is what I found. What exactly is a Port? Think of an IP address as the building address and a Port as the specific door (entry point). The port number decides which software gets the request. When a server "listens" on a port, it means the software is standing behind that door, waiting for someone to knock. The "Conflict" Rule On your local machine, only one process can bind to a specific port at a time. If you have Apache, Nginx, or another system service already listening on Port 80, your Go application will crash on startup.…
