Let consider a process iin which one state is Blocked and waiting for some input/output service. And when the service is completed then it goes to the ________.
Step by step
Solved in 3 steps
- Let I represent an execution of init(s), W of wait(s), and S of signal(s). Then, for example, IWWS represents the sequence of calls init(s), wait(s), wait(s), and signal(s) by some processes in an operating system. For each of the following sequences of calls, state the value of s and the number of processes blocked after the last call in the sequence: *(a) IW (b) IS (c) ISSSW (d) IWWWS (e) ISWWWW: Consider a system that has two processes A and B, each wants to record a scanned document on CD. Process A requests permission to use the scanner and is granted permission. Process B is programmed differently and requests the CD recorder first & is also granted permission. Now A asked for the CD recorder but the request is denied until B releases it. Unfortunately, instead of releasing the CD recorder B asks for the scanner. Answer the following question for given above scenario; Draw the Resource Allocation Graph (RAG) & also determine that there is a deadlock that exists or not. Verify the four sufficient & necessary conditions with reasons. Which one is satisfied or not?Consider a computer environment in which there are 4 magnetic drives, 2 printers, 3 scanners, and 1 optical drive. Three processes P1, P2, P3 are using these resources. At any point in time, the allocations and requests for these resources are as follows. Allocations: Magnetic drive Printer Scanner Optical drive P1 1 P2 2 1 P3 1 Requests: Magnetic drive 2 Printer Scanner Optical drive P1 1 P2 1 1 P3 2 1 Is there any way that the processes can complete without deadlock? If yes, explain how. If not, explain why not.
- We have three processes that work coordinately to serve the photo printing request(pictured below). When there is a request to print a photo, Process A reads the photo data from thedisk to Buffer 1, Process B copies the data from Buffer 1 to Buffer 2, finally Process C takes the datafrom Buffer 2 and print it.Process A ------------- Process B ------------ Process C------------------------------>| Buffer 1 |-------------------------->| Buffer 2 |----------------------------->Read from File ------------- copy ------------- print Assume each process operates on one photo at a time, both buffers' capacity can store two photos.Write a program (Pseudo code) to coordinate the three processes using semaphores. (Define thesemaphores to use and initialize their values)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)When a process is in the "Blocked" state, waiting for an I/O operation to complete. When a service is canceled, it enters one of the following states: a) State of Termination, b) State of Suspension, c) State of Running, or d) State of Readiness.
- Assume a primitive time-sharing operating system is running on a computer with 50,000 32-bit words of main memory, with the resident monitor consuming 10,000 of that. When control is to be assigned to an interactive user, the user’s program and data were loaded into the remaining 40,000 words of main memory. A program is always loaded to start at the location of the 10,000th word; this simplified both the monitor and memory management. Assume that there are four interactive users with the following memory requirements, in words: Job1: 10,000, Job2: 30,000, Job3: 1000, Job4: 5,000 Draw the main memory state diagram considering the following: (a) The monitor loads Job1 and transfers control to it. (b) The monitor decides to load Job2 and transfer control to it. (c) Next, the monitor decides to load Job3 and transfer control to it. (d) Next, the monitor decides to load Job1 and transfer control to it. (e) Next, the monitor decides to load Job4 and transfer control…For each of the following transitions between process states, give an example of one thing that would cause it. a. Run → Ready b.

Give a brief explanation of your response.Two processes P1 and P2 as stated below are up for execution where they share a variable A that is common to both. Before either process begins execution, A is set to 6. The code mentioned below also uses a binary semaphore S that is being shared. P1 P2 int P: P11: P = A*2; P12: A =P; signal (S); int Q; P21: wait (S) P22: Q = A+1; A= Q; Before any of the processes begins its execution, S is set as 0. State all the different possible values of A after both processes finish executing.
