Which of the following statements is false?
a. Use list method extend to add all the elements of another sequence to the end of a list (this is the equivalent of using +=). b. The following code adds all the characters of a string then all the elements of a tuple to a list: sample_list = [] s = 'abc' sample_list.extend(s) t = (1, 2, 3) sample_list.extend(t) c. Rather than creating a temporary variable, like t, to store a tuple in Part (b) before appending it to a list, you might want to pass a tuple directly to extend. In this case, the tuple’s parentheses are optional, because extend expects one iterable argument. d. All of the above statements are true.
A client makes remote procedure calls 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, and (ii) if it has two threads that can make requests concurrently on a single processor. You can ignore context-switching times. Is there a need for asynchronous RPC if client and server processes are threaded?
