yum is layered on top of RPM.  That is, yum uses rpm itself to actually
manage packages.  yum adds several additional features/functions:

1) It deals with dependencies (rpm only complains about dependencies,
but makes no attempt on its own to resolve dependencies).

2) It deals with updates from one (or more) repositories.  A repository
is a collection of RPMs, from which updates and/or dependencies can be
resolved as well as a source of packages to install.
