Need some DNS Forwarder Clarification

Hey guys,
So I'm finally getting serious about finishing my MCSA, and in the process trying my best to get my head around DNS. So based on my limited knowledge so far, One should almost never use a forwarder instead use a stub zone? And from my understanding stub zones only have the minimal records like about the name server, SOA and A records. And supposedly if any of this changes it automatically updates in the stub zone. However I'm not clear on how a forwarder zone updates if it updates at all. And what parts of it update like the records hosted or just like stub zone only the SOA, A, and name server?
Thanks in advance,

Contrasting stub zones and conditional forwarders
As per above comment, no such thing as a forwarder zone. Right click dns server, go to properties and check out the forwarder tab.
The stub zone does not contain A records either, they contain:
The start of authority (SOA) resource record, name server (NS) resource records, and the glue A resource records for the delegated zone.
The IP address of one or more master servers that can be used to update the stub zone.

A sub-domain would be used for massive implimentations or possibly distance offices over crap links, and some other reasons, maybe to divide up management of different sections of the DNS infrastructure.
A delegation isnt going to provide full functionality that a subdomain would. In the case of a delegation, the delegated server is just working for the primary server and in a subdomain setting the subdomain DNS servers are running their own game.
