Revision 126571968 of "Quad (Star Trek)" on enwiki

A '''quad''' is a measurement of data size on the [[science fiction]] show ''[[Star Trek]]'', including "kiloquads," "gigaquads," and "teraquads."

The exact size of these measurements has never been divulged in the show, but are presumed to be extremely large. A line from [[Data (Star Trek)|Data]] in the Italian dialogues in "[[The Measure of a Man (TNG episode)|The Measure of a Man]]" translates this unit as [[Quadrillion|Quadrillions]] of [[Bit|Bits]].

In the ''[[Star Trek: Voyager]]'' episode "[[Lifesigns (Voyager episode)|Lifesigns]]", [[The Doctor (Star Trek)|The Doctor]] states that his program consists of more than 50 million gigaquads of memory.

Another example is in another ''[[Star Trek: Voyager]]'' episode "[[Twisted (Voyager episode)|Twisted]]" where Lt. [[B'Elanna Torres]] states that 20 million gigaquads of new information has been input into the ship's computer.

And yet another example is in another ''[[Star Trek: Voyager]]'' episode "[[Threshold (Voyager episode)|Treshold]]" where Lt. [[B'Elanna Torres]] states that 5 billion gigaquads of new information has been input into the ship's computer after downloading it from the shuttle that reached warp 10 with [[Tom Paris]].

In the ''[[Star Trek: Voyager]]'' episode "[[Someone to Watch Over Me (Voyager episode)|Someone to Watch Over Me]]", [[Seven of Nine]] collected 30,000 gigaquads of information on the subject of romance.

Given the aforementioned, it is reasonable to assume that a "quad" is 10<sup>15</sup> units, but that being unspecified it may like the term "[[Word (computer science)|word]]" in present-day computing wherein the exact size is determined by the machine architecture. If this is the case, a "quad" using a "word-size" of one bit would be more-or-less equal to a present-day "[[petabit]]" or 10<sup>15</sup> bits.

==Trivia==

The '''Quad''' is used as a unit of hard disc and memory space in [[Uplink (computer game)|Uplink]].
