Starfighter
Starfighters are vehicles commonly found in science fiction. Usually having a single pilot, armed with guided and unguided weaponry, agile and fast, they are the science fiction equivalent to modern-day jet fighters. Starfighters often lack FTL drives and are therefore dependent on larger carrier spacecraft for interstellar transportation.
Practicality
As was discussed at Atomic Rockets and at this Stardestroyer.net thread, starfighters are probably not a logical vehicle to use in space combat, as they have no real advantages that a larger ship doesn't already have.
