problem1. Draw the structure of the network operating system.
problem2. Distributed operating systems can be categorized in multiprocessor and multicomputer operating systems. Compare distributed operating systems with network operating systems in terms of degree of transparency, number of copies of the Operating systems, basis for communication and openness.
problem3. Provide three benefits of the distributed system.
problem4. A client creates remote procedure calls to a server. The client obtains ten milliseconds to compute the arguments for each and every request, and the server receives 20 milliseconds to process each request. The local operating system processing time for each send or receive operation is 1 millisecond, and the network time to transmit each request or reply message is 6 milliseconds Marshalling or un-marshalling takes 1 millisecond per message. Evaluate the time taken by the client to generate and return from one request. Supplement your answer with the suitable diagram showing the valid steps for RPC.
