12. Thin Client Model

13. Fat Client
some extent processing is included
on client side basically share the
processing load on client side also
that was not in thin client Model

14. Advantages:
Execution fast, share the load of
processor, better utilization of resources
Disadvantages:
complicated system structure ,heavy up
gradation , cost replacement and
compatibility issues.

15. Zero Client Install
Back to thin client but some
application like browsing window is
on client side (GUI is integrated on
client side)
