Tank: a tank is a container; it holds your eliquid just as a gas tank in a car holds the gas.
Atomiser: the atomiser has the heating coil that vaporisers the eliquid
Cartomiser: a cartomiser is designed to be a disposable system containing the heating coil and it can hold a small amount of eliquid also, so it functions as a micro tank. Cartomiser = Cartridge Atomiser; cartridge meaning use and dispose of when done.
