1 SAGAR INSTITUTE Q. 2 Write the goals of UNIT NO.: I Q. 1 Explain distributed systems? distributed systems? Q. 3 Write two advantages and disadvantages of DS? Q. 4 Explain distributed computing model? Q. 5 What is the role of middlewaree in a distributed system? Q. 6 Why is it always a good idea to aim at implementing the highest degree of transparency possible? Q. 7 Name five reasons why to build distributed systems? Q. 8 What is the difference between a client/ /server and a distributed system Q. 9 Is a three-tier architecture a distributedd system? Q. 10 Why do we not build every system as a distributed system? Q. 11 Explain what is meant by (distribution) transparency? Q. 12 What are various implementation techniques of distributess system? Q. 13 Explain various types of failures in distributed system? Q.14 What is the main objective of distributed systems? What are the challenges? Q.15 Explain work station server model? Q.16 Point out the requirement of distributedd operating system? Q.17 What are the important issuess which are used in security of distributed system Q.18 (a) What are the eight dimensions of transparency in distributed systems? (b) What is the main objectivee of distributed systems? What are the challenges?
2 Q.19 Why is it sometimes so hard to hide the occurrence and recovery from failures in a distributed system? Q.20 Describe the Architecture for Distributed System. Q.21 Explain the Hardware and software concept of distributed system. Q.22 Explain the issues in designing a distributed systems?
3 SAGAR INSTITUTE ANUPAMA JAIN UNIT NO.: II Q.1 Define tightly and loosely coupled system? Q.2 Q.3 Describe Structure of Share Memory Space. What is Thrashing? Q.4 Explain consistency model? Q.5 Explain the term Naming? Q.6 What is meant by a virtual organization,give a hint on how such organization could be implemented? Q.7 Executing nested transactionss requires some form of coordination. Explain what a coordinator should actually do. Q.8 Q.9 Q.10 Scalability can be achieved by applying different techniques. What are these techniques? Explain distributed d file system architecture? What is an open distributed system and what benefit does opennesss provide? Q.11 Explain issues in designing DSM? Q.12 Define Consistency Model in short Q.13 Describe Naming and its Features. Q.14 Explain DSM Architecture? Q.15 write down different file sharing semantics? Q.16 Explain resource sharing in distributedd file system? Q.17 Explain whether or not NFS is to be considered a distributed file system.

Q,7 Why is computer clock synchronization necessary? Q.8 What is File Catching Scheme, File Application & Fault tolerance. Q.9 Suppose that two processes detect the demise of the coordinator simultaneously and both decide to hold an election using the bully algorithm. What happens? Q.10 Many distributed algorithms require the use of a coordinating process. To what extent can such algorithms actually be consideredd distributed? Q.11 Name at least threee sources of delay that can be introduced between WWV broadcasting the time and the processors in a distributed system setting their internal clocks. Q.12 Explain bully and ring algorithms in details?

Q.7 What is quality of service management? Q.8 Using an automounter that installs symbolic links as described in the text makes it harder to hide the fact that mounting is transparent. Why? Q.9 Explain resource sharing in distributed database system? Q.10 Explain the Procedure of Implementing RPC Mechanism. Q.11 Discuss various distributed database system models? Q.12 Differentiate between distributed operating system & distributed database system? Q.13 Write the designing issues of distributedd database system? Q.14 Discuss in what respect are distributed computing system better than distributed database system?
