- please write with proper explanation. Question half solution is here please write what is main disadvantages of this approach? Half solve questions: Mutual Exclusion: Mutex is an abbreviation for Mutual Exclusion. It is a programme object that prevents multiple users from accessing a shared resource at the same time. When a process accesses a shared variable, it is said to be in the critical section. When no two processes are present in the critical section at the same time, this is referred to as Mutual Exclusion or Mutex. while (true) { semaphore sem = S; while (S <= 0) do no operation { S = S-1; wait (S); } /*critical section*/ while (S > 0) { S = S+1; signal (S); } /*remainder section*/ }Please define wait()'s role in process termination if you have a code example.Need Code in JavaIn a multiprogramming environment, several processes may compete for a finite number of resources. A process requests resources; if the resources are not available at that time, the process enters a waiting state. Sometimes, a waiting process is never again able to change state, because the resources it has requested are held by other waiting processes. This situation is called a deadlock. Deadlock avoidance is one of the techniques for handling deadlocks. This approach requires that the operating system be given in advance additional information concerning which resources a process will request and use during its lifetime. With this additional knowledge, it can decide for each request whether or not the process should wait. To decide whether the current request can be satisfied or must be delayed, the system must consider the resources currently available, the resources currently allocated to each process, and the future requests and releases of each process.

- What is the difference between dynamic and static libraries? A. Dynamic libraries are linked when executable libraries are added to memory, and static libraries are inked alter the program is placed in the memory B. Dynamic libraries are much larger than static libraries because external programs are built in the executable file that is added to memory C. Static libraries are linked when executable libraries are added to memory, and dynamic libraries are linked after the program is placed in the memory D. Static libraries can be linked to any program at run time however, the program has to be loaded for the dynamic library code to be used56. In the multiprogramming system, a set of processes is deadlock if each process in the set is waiting for an event to occur that can be initialized only by another process in the set. Which of the following is not one of the four conditions that are necessary for deadlock to occur? a. nonpreemption b. process suspension c. partial assignment of resources d. circular waitto design a simulator to simulate the behavior of a CPU scheduler, i.e.,choosing a process from the ready queue based on a scheduling algorithm to execute it by theprocessor. The simulator has to be implemented using C++. The simulator will consists of following classes:(i) Process: The data members of this class should store process id, arrival time in the ready queue,CPU burst time, completion time, turn around time, waiting time, and response time. The memberfunctions of this class should assign values to the data members and print them. A constructorshould also be used.(ii) Process_Creator: This class will create an array of processes and assign a random arrival timeand burst time to each process. Data members, constructor and member functions can be writtenaccordingly.(iii) Scheduler: This class will implement the scheduling algorithm. The class will maintain a readyqueue of infinite capacity (i.e., any number of processes can be accommodated in the queue). Theready queue should…
- Interrupts are system wide events that stops the execution of a currently running process. Examples of interrupts include (but are not limited to) mouse clicks, process termination, key presses, etc. Some interrupts are considered as more important to be handled first then the others. For example, a hardware interrupt such as hard drive read operation has lesser priority than a memory read. In this way, the most appropriate data structure for representing of such events is the priority queue. Demonstrate by writing an algorithm or a flowchart how to insert the following interrupts in a heap so the highest priority element should move out first. Interrupts Priorities INT 0 100 INT 10 51 INT 11 52 INT 21 54Interrupts are system wide events that stop the execution of a currently running process.

- 59. A system is in the safe state if a. the system can allocate resources to each process in some order and still avoid a deadlock b. there exist a safe sequence c. all of the mentioned d. none of the mentionedWhat describes how the principle of least privlege applies to the use of computers? A, It guarantees that no information inifially held in an object can be used outside its execution environment B, A process is allowed access only to the resources il needs to complete Its task and limit damage from a faulty process C, It is a process that can access an object in a domain only if that domain has a key that malches one of the locks of the object D It is the use of access controls to monitor and limit access to applications, programs, and websites during specific times of use.Cooperating Processes: Select all of the following statements that are true. The bounded buffer solution to the producer-consumer problem discussed in class allows at most BUFFERSIZE-1 items in the buffer at the same time. Ordinary (unnamed) pipes provide a solution for unidirectional communication between related processes. A process is not able to create a pipe to itself. A solution for inter-process communication always relies on approaches for message passing. A process is cooperating if it can affect or be affected by the other processes executing in the system. At the Unix command level, it is possible to use pipes to channel the output of one command into another.
