If can, give one safe sequence?QUESTION TWO A. (i) Describe Banker’s algorithm for deadlock avoidance with supporting example (ii)Consider a computer system with has four identical units of a resource R. There are three processes each with a maximum claim of two units of resource R. Processes can request these resources in anyway, that is, two in one shot or one by one. The system always satisfies a request a request for a resource if enough resources are available. If the process doesn’t request any other kind of resource, show that the system never deadlock B. Give a solution for the following synchronization problem using semaphores (i)Producer- Consumer Problem (ii)Readers- Writers Problem C. List out the issues in preprocessor scheduling that causes performance degradation in multiprocessor systemsConsider the following snapshot of a system in which five resources A, B, C, D and E are available. The system contains a total of 2 instances of A, 1 of resource B, 1 of resource C, 2 resource D and 1 of resource E. Do the following problems:• Convert this matrix representation to a resource allocation graph.• Use the deadlock detection algorithm to determine whether the system contains a deadlock. Which processes are involved in the deadlock?• While you are use the deadlock detection algorithm, add and remove directed edges of the resource allocation graph.

Correct answer will be upvoted else downvoted. scale has a strange deformity: if the absolute weight on it is by and large x, it will detonate. Would he be able to put all n gold pieces onto the scale in some request, without the scale detonating during the interaction? Provided that this is true, assist him with tracking down some conceivable request. Officially, rework the exhibit w so that for every I (1≤i≤n), ∑j=1iwj≠x. Input The input comprises of various experiments. The primary line contains an integer t (1≤t≤1000) — the number of experiments. The primary line of each experiment contains two integers n and x (1≤n≤100; 1≤x≤104) — the number of gold pieces that Phoenix has and the load to keep away from, individually. The second line of each experiment contains n space-isolated integers (1≤wi≤100) — the loads of the gold pieces. It is ensured that the loads are pairwise unmistakable.

- Implement this algorithm in C program . Show the gantt chart as output. Round-robin (RR) is one of the algorithms employed by process and network schedulers in computing. As the term is generally used, time slices (also known as time quanta) are assigned to each process in equal portions and in circular order, handling all processes without priority (also known as cyclic executive).Case 3: Now consider the same below code but the semaphore m1 initialized to 1 and m2 initialized to 1. Code for Process P0 Code for Process P1 While(true){ m1.acquire(); m2.acquire(); Critical section m2.release(); m1.release(); } While(true){ m2.acquire(); m1.acquire(); Critical section m1.release(); m2.release(); } a) Mutual Exclusion: b) Progress: c) Bounded Waiting:Consider a database buffer manager that uses 1GB of main memory andkeeps data on a hard drive which reads 100MB per second and takes 10 milliseconds per disk seek. (a) Assume that (1) the size of each disk block is 10KB and (2) for each block keptin the buffer, the probability that the buffer manager can handle the next data request usingthat block (i.e., the probability that the block contains the requested data) is 5 · 10-6. Inthis case, calculate the expected data access time (i.e., how much time the buffer manageron average would spend to provide a requested disk block). For this calculation, assume that(1) the buffer manager runs the algorithm explained in Section 13.5.1 of the textbook, (2) thebuffer is already full (i.e., the entirety of the 1GB buffer space is already used to hold 105 diskblocks), and (3) no disk blocks are updated (i.e., no need to write dirty blocks back to thehard drive). Also, ignore the time spent for reading/writing data in the main memory.(b) Assume…
