Personal Access Display Device
In use since the 21st century, the acronym was first used for a hand-held computer and interface early in the 22nd century and well into the present
Consisting of a large touchscreen display and minimalistic manual interface or control panel (generally only one or two buttons), the typical PADD is used for a variety of functions, including logging crew manifests, compiling duty rosters or diagnostic reports, entering personal data, and/or accessing library computer systems using the LCARS Interface.
Varying in size, shape and specification, PADDs are often distinguished by the species of their manufacturer or user. Earth Alliance and Federation Starfleet PADDs are generally flat and rectangular in shape, while Klingon and Cardassian PADDs are often more angular. Ane PADDs do not even have a visual interface. They are a small box worn around the neck.
