Common names vs IUPAC

Im pretty confused on the difference between common names and IUPAC. In the course reader it says that iso and neo are for common names but in the book they sometimes combine the use of iso with IUPAC. Also what is the difference between Neo and tert-. They both have the same structure so when do you use which?

Most of the common names are easy to remember, and they do not contain digits, prefixes, and suffixes, unlike IUPAC. In the IUPAC naming the suffix is added to the functional group while in common names the name of the functional is written as the example. The example CH3CH2OH, the IUPAC name is ethanol and common name is ethyl alcohol. (A neo group is a group that has three methyl groups at the end and AT LEAST five carbons total, ie there is a secondary carbon connecting the branching side chain to the main chain. A tert-butyl group is a branching side chain that contains three methyls at the end and connects to the main chain via the tertiary carbon (once it is bonded to the chain, it is quaternary)-Chem_Mod.
