15. It is also known that user credentials may be available in a remote database. The wanted user credentials need to be downloaded from a remote database. While the main thread executing the local processing, because an external database is accessed over the Internet, data accessing is executed in another thread. As the remote data is downloaded in a thread, the data needs to be passed back to the main thread. The following statement ensures that the main thread is updated on the main queue. DispatchQueue._______._______ { // do something here }

true or false a. All of the instructions in a System function call in a user-program are executed in kernel-mode. b. A process immediately upon creation at t=0 creates 10 threads; each of the threads intends to sleep for 2sec and then execute code for 4sec. In the mean-time the process terminates after the thread creation task that lasts 1sec. It is possible that the wall-clock (outside clock) time of the execution of a thread will be more than 40sec. c. The PCB of a process is stored in an individual process's memory in user-space.
