Step by step
Solved in 2 steps
- Process States: Select all of the following statements that are true. Hardware interruptions are the only causes for process state changes. The process state ZOMBIE is assigned to a process that is terminated and removed from memory, but still has an entry in the management structures. A process in the state WAITING/BLOCKING can directly change to the state RUNNING when a respective signal arrives. The process state "SWAPPED OUT AND BLOCKED" is assigned to a process that is currently blocked and not in main memory. A child process whose parent has terminated is referred to as an orphan. A parent process may terminate the execution of its children processes.83. A state is safe, if : a. the system does not crash due to deadlock occurrence b. the system can allocate resources to each process in some order and still avoid a deadlock c. the state keeps the system protected and safe d. all of the mentionedProcesses: Select all of the following statements that are true. A process in the state RUNNING can directly change to the state WAITING/BLOCKING. The short-term scheduler mainly controls the degree of multiprogramming. The process table is an entry in the process control block.
- Critical Sections - Select all of the following statements that are true A critical section is a segment of code in which a process has write-access to data or resources that are shared with at least one other process. Every process waiting to enter a critical section must be allowed to enter it at some point. No eternal waiting must be possible. In a system consisting of n processes, a critical section protected by a mutex variable can be accessed by more than one process at a time. A process not executing in a critical section must not prevent other processes from entering the critical section. Critical sections must never contain data shared by multiple processes. O DELL WCascading termination occurs when the parent process ends in one of the following ways: a) Normally or abnormally b) Abnormally c) Normally d) None of the above.81. Given a priori information about the ________ number of resources of each type that maybe requested for each process, it is possible to construct an algorithm that ensures that the system will never enter a deadlock state. a. minimum b. average c. maximum d. approximate
- 107. To _______ to a safe state, the system needs to keep more information about the states of processes. a. abort the process b. roll back the process c. queue the process d. none of the mentionedSeveral concurrently and the outcome of the execution depends on the particular order in which the access takes place; this is called a/an processes access and manipulate the same data A Shared memory condition B Race condition C Multi- processing D Process synchronizationSelect correct Given a priori information about the ________ number of resources of each type that maybe requested for each process, it is possible to construct an algorithm that ensures that the system will never enter a deadlock state. a) minimum b) average c) maximum d) approximate
- Computer Science Write a “C” program that creates a number of zombies (1 through n) processes as specified in the command line arguments to the program: zombiefier –n 10 creates 10 zombies.

Q Search ** LWhen a process is waiting for an I/O operation to finish, it is said to be in the "Blocked" state.
