Byte
From Memory Alpha, the free Star Trek reference
(Redirected from Petabyte)
A byte is a unit of computer storage.
When the Bynars performed a computer core-dump from Bynaus in the USS Enterprise-D, they filled every byte of free space in the starships computer core. (TNG: "11001001")
[edit] Comparative list of storage measurement
- Gigabyte(GB) = 1 billion bytes; Terabyte(TB) = 1 trillion bytes; Petabyte(PB) = 1 quadrillion bytes; Xbyte = size unknown (could refer to a xonabyte(XB) which equals 1 octillion bytes)
- D'Jamat deleted 19.3 XB of data Enterprise had collected on the Delphic Expanse spheres. (ENT: "Chosen Realm").
- According to Wesley Crusher, nanites used in the 24th century had "gigabytes of mechanical computer memory". (TNG: "Evolution")
- Henry Starling noted that when Captain Janeway and Commander Chakotay attempted to download his database, they had downloaded 3,000 gigabytes, or three terabytes, of data when Starling forced them to terminate their download. (VOY: "Future's End")
- Petabyte = 1 quadrillion (1 × 1015) bytes
- Data was built with the ultimate storage capacity of 800 quadrillion bits. At 8 bits per byte, it can be calculated that Data has 100 petabytes, or 100,000,000 gigabytes, of memory. (TNG: "The Measure Of A Man")
This term was never specifically used the episode, but is calculated from the description given on Data's abilities.
[edit] Background
The term "byte" was apparently replaced by "quad" when the Federation started using a different computer language other than binary, which uses two numerals instead of four.
