External interfaces used to connect different devices with cables are called ports.
These include network connections as well as USB connections.
In addition to that the term “port” is also used if it comes to socket strips on a computer mainboard.
An additional graphic card is plugged in for example in the socket strip called PCI port.
It has to be noted that the term port is also used if it comes to the description of data exchange between a client and a server.
To avoid confusion it is good practice to add the name software or hardware as prefix to the term port.
