EDI

Mass Effect 3 Codex Entry
The Enhanced Defense Intelligence, or EDI, serves as an information source and cyberwarfare defense system on the rebuilt Normandy SR-2. The ship's crew can access EDI at any terminal or through radio contact.

During an attack from a Collector vessel, pilot Jeff "Joker" Moreau gave EDI full access to the Normandy's systems, allowing the ship to escape. Although EDI retains the control that Moreau gave her, she is usually content to advise the organic crew members who fly and maintain the ship.
