Tunisian Crochet (aka Afghan or Tricot Crochet):

This type of crochet uses an elongated hook with a stopper on the handle end. Each row is worked twice and the work is never turned.  A dense fabric is created with a definite front and back side and makes an ideal base for cross-stitching. (source: Wikipedia).

Double Ended Crochet: (aka Cro-Hook; Cro-Knit; Crochet on the DoubleTM; Crochenit) :

All of the above can be accomplished with a Double Ended Crochet Hook. Each hook end is the same size. Because a hook is on each end, two colors of yarn/thread can be handled at once and freely interchanged. (source: Wikipedia).
