The Halo 4 terminals are short videos that are unlocked once you find their locations on the various locations of the game. There are 7 Terminals in Halo 4 hidden in the Campaign. Accessing the Terminals will unlock a video on Halo Waypoint. Like the terminals in Halo: Combat Evolved Anniversary, the Halo 4 terminals feature animated and voiced cinematics similar to motion comics. Fictionally, the terminals are presented as visits to the mysterious store of information known as the Domain, once used by the Forerunners.
