💡 What is a Port (in networking)?

A port is like a door or channel on a computer/server that’s used for communication between devices.

Imagine:

• The IP address is like the building address (e.g., 192.168.0.10).
• The port number is like the apartment or room number (e.g., port 3000).

🧠 Why Do We Need Ports?

Because many applications/services run on the same machine. Ports help route network traffic to the correct app.
