Additionally to all the correct answers, a 'port' can also mean something completely different 'in networking'.

It can be a physical socket in a network equipment, like 'Ethernet port'. Or it can be a virtual equivalent of such, e.g. when connecting virtual machines on a host - that could be called a 'logical port'.

Those can sometimes be used interchangeably with 'interface' or 'device', but it depends on convention used in particular system or environment.
