Corridor is An enclosed passageway; rooms usually open onto it cowboy...

Many times when people say corridor, they're talking specifically about hallways in older building like in a castle or something. Think of Hogwarts in Harry Potter. That sort of setting. That's not always the case, but more often than not it is. Very few people would refer to a hallway in a modern building as a "corridor".

Hello Ashehri, "Corridor" beside its concrete mostly used meaning of an enclosed passageway with rooms usually opening into it ,on a larger scale it could also mean a strip of land connecting a country with another or giving it a route to the sea through another country. It could also refer to a usually densely populated region characterized by one or more well-traveled routes used by railroad, airline, or other carriers: The Northeast corridor extends from Washington, D.C., to Boston. In Aeronautics a 'corridor' indicates a restricted path along which an aircraft must travel to avoid hostile action, other air traffic. In the field of aerospace it refers to a carefully calculated path through the atmosphere along which a space vehicle must travel after launch or during reentry in order to attain a desired orbit, to avoid severe acceleration and deceleration, or to minimize aerodynamic heating.

Its like a hallway in a building or house.

A long passage in a building or train,especially with rooms on either side. Ex: Her office is at the end of the corridor on the right.
