The transporter room is part of a starship or space station which is specially outfitted to transport lifeforms and small, inanimate objects.
The number of transporter rooms varied per ship or station, the main criteria being the ability to evacuate all personnel within a specified time. All key components which were needed for transport were fitted in this room and the one just below.
Some starships, such as the NX-class Enterprise, did not have a transporter room. The area surrounding Enterprise's transporter was instead situated between two corridors to which the transporter alcove was directly adjoined, on either side. (Star Trek: Enterprise)
A transporter room was usually manned by a transporter operator.
