The Flop: The first three community cards revealed in Texas Hold'em. These cards are shared by all players and are used to form the best five-card hand.
The Turn: The fourth community card in Texas Hold'em, revealed after the flop betting round concludes. Also called the "fourth street."
The River: The fifth and final community card in Texas Hold'em. Once the river is dealt, players have all information needed to determine their final hand strength.
