Please answer the following Operating Systems Quetion and its two parts: Part A: A distributed system using mailboxes has two IPC primitives, send and receive. The latter primitive specifies a process to receive from and blocks if no message from that process is available, even though messages may be waiting from other processes. There are no shared resources, but processes need to communicate frequently about other matters. Is deadlock possible? Discuss. Part B: One way to prevent deadlocks is to eliminate the hold-and-wait condition. In the textbook it was proposed that before asking for a new resource, a process must first release whatever resources it already holds (assuming that is possible). However, doing so introduces the danger that it may get the new resource but lose some of the existing ones to competing processes. Propose an improvement to this scheme. * Please answer both parts correctly, and I will provide a Thumbs Up. Thanks.

Someone once observed that "the difference between roles and groups is that a user can shift into and out of roles, whereas that user has a group identity (or identities) that are fixed throughout the session." Consider a system such as a System V-based UNIX system, in which a process can have exactly one group identity. To change groups, users must execute thenewgrpcommand. Do these groups differ from roles? Why or why not?
In a process using threads, is there one stack per thread, or one stack per process? Explain. In the final version of the process state model, we have a state “blocked and swapped.” If the goal of blocking a process is to prevent the blocked process from wasting resources, why do not we only have “blocked and swapped”? Why a separate state “blocked”? Explain your answer. Linux systems do not allow all signals to be caught or ignored. Suppose they did; how would you stop an application that has ignored all signals from running? Assume at time 5, no system resources are being used except the processor and memory. Given this, consider this sequence of events: at time = 5: P1 executes a command to read from disk unit 3; at time = 15: P5’s time slice expires; at time = 18: P7 executes a command to write to disk unit 3; at time = 20: P3 executes a command to read from disk unit 2; at time = 24: P5 executes a command to write on disk unit 3; at time = 28: P5 is swapped out; at time = 33:…
For example, Computer A can communicate with computer C by using TELNET. At the same time, computer A communicates with computer B by using the File Transfer Protocol (FTP). For these processes to receive data simultaneously, we need a method to label the different processes. Could you explain that method?
An e-mail system filters incoming e-mails with a whitelist (e-mails from senders on the whitelist are accepted), a blacklist (e-mails from senders on the blacklist are deleted), and the Spam assassin tool (e-mails that do not pass this check are marked as spam). The system will run on a single-core server machine, but may be moved to a multi-core server if the load gets too high. A) Which architectural style will you use.B) Draw a context diagram that describes your system.
Two processes CLT and SRV are involved in remote invocation with CLT acting as the client,while SRV acts as the server.(a) Highlight the underlying request-reply protocol using its primitives. (b) The request issued by C was not replied to on time. Explain the steps taken by bothprocessesusing the at-least-once semantics.(c) Explain the steps taken by both processes using the exactly-once semantics when CLT does not receive the response.

For a system, the resource allocation state is given below: Available = (2 4 1 1) (a) Is this system in a safe state? Justify your answer. (b) If a request from process P0 arrives for (0 2 0 0), can the request be immediately granted? Justify your answer
List an advantage for a Preemptive Scheduler in an OS. Is there also a clear disadvantage? If so, what is the nature of it? (short answer is ok)
9. The methods for dealing with the deadlock problem is a. Use a protocol to make sure that the system never enters in to the deadlock state. b. Allow the system to enter a deadlock state and then recover. c. Ignore the problem, and pretend that deadlocks never occur in the system. The UNIX operating system uses this solution. d. all of these
A system provides support for user-level and kernel-level threads. The mapping in this system is one to one (there is a corresponding kernel thread for each user thread). Does a multithreaded process consist of (a) a working set for the entire process or (b) a working set for each thread? Explain.
