The many-to-many way of mapping user threads to kernel threads generally incurs lower overhead than the one-to-one model. True False When one process wants to exchange data with another process running on a remote machine over a network, it should choose the shared memory method because it is more reliable than message passing. True False In many-to-many way of mapping user to kernel threads, let N user threads be mapped to M kernel threads --- it is not uncommon to have M>N. True False When creating a thread in Java, the more widely used way is to use a function called CreateThreado to implement an interface named Runnable, write the run() method to extend a class called Thread, rewrite the run() method to instantiate an object of the Thread class
