LCARS

In the Star Trek fictional universe, LCARS (; an acronym for Library Computer Access/Retrieval System) is a computer operating system. Within Star Trek chronology, the term was first used in Star Trek: The Next Generation and in subsequent shows. In a real-world context, "LCARS" is frequently used to describe the style of the computer displays of the LCARS system, especially the screens from The Next Generation and Voyager.
