[Marvin Hunkin]

Hi.
could any one give me a overview of what the mac and linux operating systems look like and how they function.
have tried googling it and using altavista.
cannot seem to find a simple over view of the interface of these operating systems.
need to do an assignment a report on different operating systems.
can any one help.
cheers Marvin.
ps tried the terms gui linux interface over view, operating system interface and guis.
and tried introduction to mac and linux.
