Question

A process may consist of multiple threads of execution all of which share the resources allocated to the process. True False Each thread in a multithreaded process has its own execution state. True False Each thread in a multithreaded process has its own context. True False Each thread in a multithreaded process has its own stack. True False Threads in a multithreaded process share the process id but have individual thread ids. True False Thread creation/termination/switching is way faster than process creation/termination/switching. True False Inter-thread communication is way faster than inter-process communication as long asthe threads belong to the same process. True False Designing an application as a multithreaded process naturally leads to a modular program structure. True False Having multiple kernel level threads in a process speeds up its execution in a multiprocessor because multiple threads of the process can run concurrently on multiple CPUs. True False Having multiple kernel level threads in a process will not lead to faster execution of the process on a uniprocessor because only one thread can run at a time. True False Kernel is aware of the existence of both kernel level threads and user level threads. True False When one kernel level thread makes a blocking call, all the other kernel level threads in the process become blocked as well. True False When any user level thread makes a blocking call, the process as a whole becomes blocked. True False User level threads allow multiple blocking function calls to be made in parallel. In other words, while a user level thread is blocked, other user level threads can make their own blocking function calls. True False A process with multiple kernel level threads can execute much faster than a process with a single thread even on a uniprocessor. True False A process with multiple user level threads can execute much faster than a process with a single thread. True False User level thread creation/termination/switching is way faster than kernel level thread creation/termination/switching because user level thread operations do not require switching to the kernel mode. True False A programmer can control the order in which user level threads are scheduled. True False A programmer can control the order in which the kernel level threads are scheduled. True False User level threads lead to much more portable applications
