- COPY FROM CHEGG == DISLIKE AND REPORT Assume that a finite number of resources of a single resource type mustbe managed. Processes may ask for a number of these resources and will returnthem once finished. As an example, many commercial software packagesprovide a given number of licenses, indicating the number of applications thatmay run concurrently. When the application is started, the license count isdecremented. When the application is terminated, the license count isincremented. If all licenses are in use, requests to start the application aredenied. Such a request will be granted only when an existing license holderterminates the application and a license is returned. The following program segment is used to manage a finite number of instancesof an available resource. The maximum number of resources and the number ofavailable resources are declared as follows: #define MAX_RESOURCES 5 int available_resources = MAX_RESOURCES; /** When a process wishes to obtain a number of…Assume that there are the following processes in the deadline scheduler queue: Process Arrival Runtime Period Deadline 1 0 2 12 10 2 2 4 20 16 3 4 3 15 14 Complete the following schedule so each of the processes adheres to the deadline policy by replacing a dot with a process number (as necessary): TIME: 01234567890123456789012345678901234567890123456789 PROCESS: 112222333.......................................Solve the following bankers Algorithm and find a save sequence 5 processes P0 P1 P2 P3 P4; 3 resource types A (20 instances), B (10 instances), and C (14 instances).

- Facts: Facts about Deadlock Deadlock is a situation that occurs in OS when any process enters a waiting state because another waiting process is holding the demanded resource. Deadlock is a common problem in multi-processing where several processes share a specific type of mutually exclusive resource known as a soft lock or software. Deadlock is a situation where a process or a set of processes is blocked, waiting for some other resource that is held by some other waiting process. It is an undesirable state of the system. The following are the four conditions that must hold simultaneously (Links to an external site.) for a deadlock to occur. Mutual Exclusion –A resource can be used by only one process at a time. If another process requests for that resource then the requesting process must be delayed until the resource has been released. Hold and wait –Some processes must be holding some resources in nonshareable mode and at the same time must be waiting to acquire some more…*Assume that there are three processes P1, P2, P3and P4 and four resources R1, R2, R3 and R4. The processes make the requests for resources in the following order: P1 requests R1 P2 requests R2 P3 requests R3 P4 requests R4 P1 requests R2 P2 requests R3 P3 requests R4 P4 requests R1 Assume that there is only one instance of resources R1, R2, R3 and R4. Draw a resource allocation graph and find out if the above processes will deadlock or not? and What are the four necessary conditions for a deadlock to happen?Question: The purpose of this project is to design and implement a distributed storage system. The system's architecture is inspired bythe abstract architecture for distributed file systems. Among the components, we have a client and multiple instances of a server. We adopt an asynchronous peer-to-peerreplication among the server instances with a replication factor of three. The system supports two operations: read and writeobjects. Each object is represented in a JSON format and stored in a local file for each instance of the server. Note that the fileshave a limited size of 30 MB. As well each object has a key (a string) attached to it. Finally, we use Kafka as a middlewarebetween the client and the server(s) To write an object, the JSON content and the key are sent to the server through Kafka. When the write operation succeeds, theclient receives an acknowledgement from each server. A write operation with an existing key replaces the existing object.Moreover, the client sends a…
