A client makes remote method invocations to a server. The client takes 5 milliseconds to compute the arguments for each request, and the server takes 10 milliseconds to process each request. The local operating system processing time for each send or receive operation is 0.5 milliseconds, and the network time to transmit each request or reply message is 3 milliseconds. Marshalling or unmarshalling takes 0.5 milliseconds per message. Calculate the time taken by the client to generate and return from two requests: (i) if it is single-threaded; (ii) if it has two threads that can make requests concurrently on a single processor.

e Show vour formula and intermediate steps . The single-threaded means that sending a second request should be followed after receiving the reply of a first request . The server can process a single request at a time. Assume error free network
