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.
Alkanes are saturated hydrocarbons. Saturated means that the hydrocarbon has only single bonds and that the hydrocarbon contains the maximum number of hydrogen atoms for each carbon atom. Unsaturated hydrocarbons contain multiple bonding and contain less than the maximum number of hydrogens per carbon.
