Torx bits are similar to allen keys in being six sided but where the allen key is hexagonal the torx bit is a six lobed star shape - hexalobular.

TORX head screws resist cam-out better than Phillips, Pozidriv or slot head screws. Phillips screws were specifically designed to make the driver to cam out, to prevent over-tightening, TORX heads were designed to prevent it.  This can increase driver bit life by ten times or more.
