Supply is a terran gameplay counter limiting the size of a terran force. The number of counters is increased by constructing select units, to a maximum of 200. New units may be produced so long as the cumulative supply "cost" of all active units does not exceed the number of available supply counters.
In strategy discussions, supply levels may be denoted as x/y, where x is the supply used, and y is the total available supply.
Here is a list of how much supply each unit takes in StarCraft:
