Control

In StarCraft, each Protoss player has two Control counters - the first refers to the amount of supply being consumed by the player's units and the second refers to the amount of total supply available. The difference in the two numbers is the amount of supply that is still available for constructing additional units. Once the difference in the two numbers reaches zero, a player will not be able to construct any additional units. Hidden is a 200 point Control max, the limit beyond which your production structures can no longer turn out units no matter how many supply production objects you create.

Here is a list of how much Control each unit takes:

0.5 Control: Zergling, Scourge

1 Control: Drone, Hydralisk, Infested Terran

2 Control: Lurker, Defiler, Mutalisk, Guardian, Devourer, Queen

4 Control: Ultralisk

(Larva and Broodlings require no control)

An Overlord provides 8 control, Hatcheries, Lairs and Hives offers 10 control.
