A column ________ displays data comparisons vertically in columns

Answer the following statements true (T) or false (F)

1. If a class does not provide a method that you need, you can write your own custom method for an object of that class. 2. When you create a custom method for an object, it is automatically added to that object’s class. 3. The parameter of a custom method cannot be an object. 4. Additional properties can be added to an object by creating class-level variables. 5. Inheritance allows programmers to reuse code.

A client makes RMIs to a server. The client takes 5 ms to compute the arguments for each request, and the server takes 10ms to process each request. The local OS processing time for each send or receive operation is 0.5ms, and the network time to transmit each request or reply message is 3 ms. Marshalling or unmarshalling takes 0. 5 ms per message. Estimate the time taken by the client to generate and return from 2 requests (i) if it is single-threaded, and (ii) if it has two threads which can make requests concurrently on a single processor. Is there a need for asynchronous RMI if processes are multi-threaded?
