4.1. It was pointed out that two advantages of using multiple threads within a process are that (1) less work is involved in creating a new thread within an existing process than in creating a new process, and (2) communication among threads within the same process is simplified. Is it also the case that a mode switch between two threads within the same process involves less work than a mode switch between two threads in different processes?

Is it possible for a parent process to wait for the termination of his child process and then to continue working on his own task? How can it be done using threads where a thread could be bound to wait for the termination of another thread and then continue working on his task. Write a piece of code to demonstrate both these cases in a single program. This is the Question from System Programming

Consider an environment in which there is a one-to-one mapping between user-level threads and kernel-level threads that allows one or more threads within a process to issue blocking system calls while other threads continue to run. Explain why this model can make multithreaded programs run faster than their single-threaded counterparts on a uniprocessor computer.
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.
you are tasked with analyzing an algorithm which schedulea processes in a multiprogramming system. You are working with a computer that has two CPUs, each CPU having two threads (hyperthreading). You are studying a scenario with three processes: P0, P1, & P2., with run times of 5, 10, & 20 msecs, respectively. All 3 programs are 100% CPU bound, don't block, and always run in the CPU it's assigned to. How long will it take for these programs to complete execution. Show three different possible outcomes (and assigned process to processor, 3 different combinations and resulting total time for all three to complete)
Modern Operating Systems must tackle the challenges of Synchronization and Deadlock. 'Process Synchronization' is the task of coordinating the execution of processes in a way that no two processes can have access to the same shared data or resource. A process requesting a resource may have to wait, if the resource is not available at that time. Sometimes, a waiting process is never able to change state, because the resources it has requested are held by other waiting processes; this situation is called 'Deadlock'. In concurrent programming, a "critical section" is a part of a multi-process program thatmay not be concurrently executed by more than one of the program's thread. Let us consider a 2 processes solution: do {flag[i] = TRUE;while(flag[j]); %waitCRITICAL SECTIONflag[i] = FALSE;REMAINDER SECTION} while (TRUE);Pseudo-code of $P_i$ (the one of $P_j$ is symmetric) a) Does the given solution satisfy the mutual exclusion requirement? Explain (asimple 'yes-no' answer is NOT enough.…
