Deadlocks: Select all of the following statements that are true.A deadlock means that at least two processes cannot continue working becausethey are waiting for each other.One of the four introduced deadlock conditions is circular wait.Deadlock prevention aims to abort processes or preempt some resources whendeadlocks are detected.If a resource-allocation graph is expedient, a knot is a sufficient condition fordeadlock.The banker's algorithm's goal is to completely reduce the Maximum Claim Graph(MCG) given.

Deadlocks are a common problem in operating systems, where multiple processes compete for a limited…

Programming assignments1) Waiting line simulation in an Indian post office:In an Indian post office that not only delivers mail but also functions as a savingsbank carrying out specific transactions, a lone postal worker serves a single queue ofcustomers. Every customer receives a token # (serial number) as soon as they enterthe queue. After service, the token is returned to the postal worker, and the customerleaves the queue. At any point in time, the worker may want to know how manycustomers are yet to be served.i) Implement the system using an appropriate queue data structure, simulating arandom arrival and departure of customers after service completion.ii) If a customer arrives to operate their savings account at the post office, thenthey are attended to first by permitting them to join a special queue. In such a case,the postal worker attends to them immediately before resuming their normal serviceof mail delivery. Modify the system to implement this addition in service
Schedulers: Select all of the following statements that are true. A long-term scheduler selects which process should be executed next and allocates the CPU. The main task of a medium-term scheduler is to swap out and in processes from memory. A long-term scheduler executes much more often than a short-term scheduler. The long-term scheduler controls the degree of multiprogramming. The ready queue contains the set of all processes residing in main memory, ready and waiting to execute. Device queues refer to processes waiting for an I/O device.

Complete the following code. The goal is to implement the producer-consumer problem. You are expected to extend the provided C code to synchronize the thread operations consumer() and producer() such that an underflow and overflow of the queue is prevented. You are not allowed to change the code for implementing the queue operations, that is the code between lines 25 and 126 as shown in the screenshot. You must complete the missing parts as shown in the screenshot as well as complete the missing codes of producer and consumer. #include <stdio.h> #include <stdlib.h> #include <unistd.h> #include <time.h> #include <pthread.h> #include <semaphore.h> #include <errno.h> #include <fcntl.h> #define MAX_LENGTH_CAP 100 #define INIT -127 #define UNDERFLOW (0x80 + 0x02) #define OVERFLOW 0x80 + 0x01 #define BADPTR (0x80 + 0x03) #define CONSUMER_TERMINATION_PROBABILITY 40 #define PRODUCER_TERMINATION_PROBABILITY 30 // ============= LOCKED…

1) Design an algorithm using DFS that detects whether graph G has a cycle. State and explain running time. Graph G need not be connected. Write in Pseudocode, please. 2) BFS refresher: Suppose you have an n × n chessboard and a knight placed in one of the squares. Youwould like to find out the fewest number of moves needed to reach a given target square. Design an algorithmfor this task stated formally below: Input: An n × n chess board, a starting square S, and a target square T.Output: The fewest number of moves a knight takes to move from S to T. Write in Pseudocode, please.
