Question:
(a) Explain the similarities and differences between two different threads running in the same process and two independent processes. When would you want to use two threads in the same process? When would you want different processes?
(b) Describe the function of any two of following in the context of a remote procedure call
• Communication Module • Dispatcher • Server Stub
(c) Describe the role of a remote object reference during marshaling and unmarshalling, at both clients and servers, in an RMI system.
(d) By using examples, distinguish between a local method invocation and a remote method invocation.
(e) Briefly discuss and describe the possible RMI invocation semantics.
(f) A ‘null' RMI that takes no parameters, calls an empty procedure and returns no values delays the caller for 2.0 milliseconds. Explain what contributes to this time.
In the same RMI system, each 1K of user data adds an extra 1.5 milliseconds. A client wishes to fetch 32K of data from a file server. Should it use one 32K RMI or thirty-two 1K RMIs?
Q. Explain the Concept of Process? A process is sequential program in execution. A process states the basic unit of computation for the computer. Components of process are:

What does it mean for something to be thread-safe? By saying that X is thread-safe, we mean that if multiple threads use X at the same time, we don't have to worry about concurrenc
Conservative GC can be used for languages such as C and C++, which were not explicitly designed for garbage collection. This is a non-copying technique. A conservative garbage coll
