define bullet & blitz

I see three different ratings. What is blitz and what is bullet?

...and the 'Flash' is the fastest !

Does anyone know the range associated with each category?

I put the following search into google: bullet blitz

and the following page comes up first: http://en.wikipedia.org/wiki/Fast_chess

I guess the relevant portion is:

The different names distinguish the maximum duration of a game. Commonly used time controls are:

• Rapid or Quick: 15 to 60 minutes per player, sometimes with a small time increment per move (e.g. 10 seconds).^[1]
• Blitz: 3 to 5 minutes per side. Usually sudden death (no increment), but may also be played with a small increment.^[1]
• Bullet: 1 or 2 minutes per side.
• Lightning is a term used for either Blitz or Bullet chess, and is a general term for extremely fast chess. It can also refer to games with a fixed time (e.g. ten seconds) for each move.
• Armageddon: a single game guaranteed to produce a result, because Black has draw odds (that is, for Black, a draw is equal to a victory). To compensate, White has more time on the clock. Common times are 6 minutes for white and 5 for black, or 5 minutes for white and 4 for black. This can also be played with a small increment.

Here at chess.com, the designations quick, blitz, and standard are determined by the sum of the time bank and increment:

quick up to 3

blitz 3 to less than 15

standard 15 and up

Hey, I know that this is an old question but I think this link might be useful specifically for chess.com.
