Unsaturated means there are at least one carbon-carbon double bond. Saturated substances are: less reactive (as it only has single bonds), stronger dispersion forces, thus higher melting points then unsaturated substances---but still quite low.
The term saturated is used to refer to a compound in which all carbon-carbon bonds are single bonds and every carbon atom is connected to a different atom. A saturated hydrocarbon will contain all the hydrogen atoms possible according to the alkane general formula CnH2n+2.
