Explanation

A port is a place where boats come and go. If you think that docks and harbors are romantic, I suggest you move to a port city like Baltimore. Just as seaports and airports link countries together by enabling trade and travel, a device that links computers together is also called a port. Port comes from the Latin word portus, meaning "haven" or "harbor." You can hear this sense of a port as a place of safe arrival in the proverb "any port in a storm." On a ship, the port side is the left side. Port is also a verb, meaning "to carry."
