3 Compare processor pool model and workstation server model
4 Discuss briefly the various issues related to distributed system design.
5 How does a distributed operating system differ from a network operating
system? Explain group communication mechanism.
6 What is a distributed system? How a distributed system projects a single system image?
7 What is the main difference between stateless and stateful servers? Which servers are
used in distributed applications?
