Question

A thread is smaller than a process, so thread creation typically uses fewer resources than process creation. Creating a process requires allocating a PCB, a rather large data structure. The PCB includes a memory map, list of open files, and environment variables. Allocating and managing the memory map is typically the most time-consuming activity. Creating either a user or kernel thread involves allocating a small data structure to hold a register set, stack, and priority. True or false When the number of kernel threads is less than the number of processors, then some of the processors would remain idle since the scheduler maps only kernel threads to processors and not user-level threads to processors. When the number of kernel threads is exactly equal to the number of processors, then it is possible that all of the processors might be utilized simultaneously. However, when a kernel-thread blocks inside the kernel while invoking system calls, the corresponding processor would remain idle When there are more kernel threads than processors. a blocked kernel thread could be swapped out in favor of another kernel thread that is ready to execute, thereby increasing the utilization of the multiprocessor system True or false The primary reason for opening each website in a separate process is that web application in one website crashes, only that renderer process is that

Explanation / Answer

Correct answer is True.

Reason:

--------------------------------------------------------------------------------------------------------------------------

Correct answer is True.

Reason: Use the many-to-many threading model to written by a multithreaded program and a multiprocessor system. Here assume the

the number of processors is less than the the number of user-leavel-threads. In that case, the processors would remain idle since the scheduler maps only kernel thread and not user level threads. So, use the number of kernal threads is less than the number of processors.
