RER Trains usually come in handy for longer trips outside Paris, to the CDG Airport for instance, or to the Versaille Palace, (Chateau Versaille) but they can also serve for short connections between Metro Stations. The ticket for the RER Train is good for the Metro also. These two stystems are well intergrated although the signage in the Metro is much easier to follow.
The RER trains use an alphabet designation, a color, and a number: B 3, blue, for instance for Airport Charles Degaulle.
