RHEL 5 basic vs advanced

Hello there to the community

Question 1 : how can you tell if the RHEL 5 version you have is BASIC or ADVANCED. ?

Question 2 : except for virtualization limits on BASIC RHEL which is 2 physical CPUs and 4 virtual guest (redhat virtualization , not VMWARE) and Advanced allows unlimited CPU and virtual guest support, what are the other major differences.?
