Data pad

A data pad, sometimes rendered as datapad, is a piece of technology used by humans. Data pads are portable computer pads that store information, files, pictures, and sounds. Data pads vary greatly in size, from the size of a tablet computer to thumb-sized devices.

Dr. Catherine Halsey kept a pad of information with her about the Spartan-II candidates as she began to research them. She also appeared to have this technology on her glasses, as she could pull up and read files on them. Similar to modern day devices of the same nature, they can be password protected or in Dr. Halsey's case, sensitive to her retinas only. Data pads are used by the Spartan-IVs to insert themselves into combat scenarios throughout human history.

The TACPAD appears to be a military application of the data pad.

Trivia
They are extremely similar to the "Padd" that appears commonly in the Star Trek universe, or the datapad from Star Wars. It seems to have stemmed from today's PDAs and handheld phones.
