I can think of two possibilities. I assume since you are asking specifically about Port 1050, that you have a software firewall or a NAT based firewall.
Taking a leap into the darkness, is your router by any chance the Netcomm NB5Plus4W as that has a manufacturing defect that causes the port to be open. See the guide guide for port forwarding to close your port if this is your router.

It could be malware opening up your port or it could be your firewall.
The computer does not have to be connected to the internet at all for the port to be open, or listening.
The ports are available to see on the front and back of your computer. For instance the RJ45 port is the port that you plug in the cable to get to the Internet. If you want to see where the ports are located on the inside, just open your case and you will see them along the back of your computer. For instance, your keyboard is connected to a input port.

You have to have a program that is actually using this port for it to be "open." As long as the program is not blocked by Windows Firewall, the port will be open.
some kind of port also called a i/o port for input/output on the computer
This depends on the OS in use. In Windows, you can open a port by entering its port number through the 'Add port' function of Windows Firewall.
