Cooldown
From Liquipedia StarCraft 2 Wiki
Cooldown is the delay between a unit or building's attacks or use of certain non-passive abilities, measured in seconds.
Types of Cooldown[edit]
Attack Cooldown[edit]
Attack Cooldown is the amount of delay between the damage-dealing actions of buildings or units, measured in seconds. It is a key statistic, as combined with attack damage it defines the Damage per second (DPS) of a unit or building. To calculate DPS, a unit's attack damage is (multiplied by the attack count and) divided by the cooldown period. Attack cooldown is also an important attribute to be aware of when kiting, as the kiting units should ideally be moving during the entire cooldown period.
There are upgrades that reduce the attack cooldown of specific units, such as Adrenal Glands on the Zergling. The Terran ability Stimpack reduces the attack cooldown of the Marine and Marauder by 33%, thereby increasing the DPS of those units by 50%.

Ability Cooldown[edit]
Ability cooldown is the minimum period of time that must pass between usages of an ability, measured in seconds.
Ability use is regulated, broadly speaking, by either Energy or cooldowns. Some abilities that consume energy also have a cooldown; some abilities such as Blink and Charge only have cooldowns. When using these abilities, a clock animation will appear over the ability icon, denoting how much of the cooldown period remains. A special category of cooldown usage is the Warp Gate: whereas training a unit with other buildings delivers the unit after a set period, the Warp Gate delivers the unit after a few seconds, and the Warp Gate goes on cooldown.
Certain abilities, such as Generate Creep, have no cooldown period (or energy cost) at all and may be used continuously.
