(also "sparks") In the U.S. Navy Sparky was a nickname for enlisted men who's rating was Radioman. The name comes from the responsibilities of Radiomen to fix and work with Antennas, Radios, and other related equipment; It may also come from the Radioman (Now Information System Technician) Insignia or Rating Mark which is four Lightning Bolts or Sparks. After the Radioman rating was merged with Data Proccesing Technician to create Information Systems Technician the term Sparky was carried over to be used for sailors who were Information Systems Technician or IT's.

Note: Information System Technicians may also be referred to as "Spook" or "Ghost" since the Cryptologist merger, however Sparky and Sparks are much more common.
