Could someone have left a BLANK open?
port
It's a connection point on a network that allows data to flow in and out.
A port is a virtual connection point used in networking to allow communication between devices. For example:
I'm trying to connect to the server, but the port might be closed. - The connection point might be blocked, preventing the connection to the server.
Ports can be open or closed. An open port can allow hackers to enter a system if not properly secured, while a closed port does not allow data to pass through it.
