Homework Answers
The answer is D.
Whenever the running process changes its state to either blocked or
it terminates then the non-preemptive algorithm makes the
decision.
Add Answer to:
A non-preemptive algorithm makes a scheduling decision whenever a process requests an unavailable resource a process...

State transition diagram used for operating system management of the Process Control Block has the following states A New (Create)– In this step, process is about to be created but not yet created, it is the program which is present in secondary memory that will be picked up by OS to create the process. Ready -> Ready to run. After creation of a process, the process enters the ready state i.e. the process is loaded into the main memory. The...
Consider the set process, Find average time of following Scheduling Algorithm
Consider the set process. There arrival time start from 0, Consider your seat number as burst time also consider all time value in seconds. Find average time of following Scheduling Algorithm. Note (quantum=2) (a) Longest Remaining time first (LRTF) (Preemptive) (b) Round Robin Scheduling (LRTF) (Non- Preemptive)

The following processes are being scheduled using a preemptive, roundrobin scheduling algorithm. Each process is assigned a numerical priority, with a higher number indicating a higher relative priority. In addition to the processes listed below, the system also has an idle task (which consumes no CPU resources and is identified as I ). This task has priority 0 and is scheduled whenever the system has no other available processes to run. The length of a time quantum is 5 units....

Q.6. Consider a preemptive operating system where processes have priorities and a running process gets preempted (i.e., forced to leave the CPU) as soon as a higher priority process is ready to run. The life cycle of a process, other than the very first process, begins with a "spawn" by another process and ends with either a regular "exit" by the process or a "terminate (process_id)" command by another process of equal or higher priority. COMP 346 – Fall 2019...

Description In this homework, you are asked to implement a multithreaded program that will allow us to measure the performance (i.e, CPU utilization, Throughput, Turnaround time, and Waiting time in Ready Queue) of the four basic CPU scheduling algorithms (namely, FIFO, SJE PR, and RR). Your program will be emulating/simulating the processes whose priority, sequence of CPU burst time(ms) and I'O burst time(ms) will be given in an input file. Assume that all scheduling algorithms except RR will be non-preemptive,...

Write a C program for:
One technique for dealing with deadlock is called “detect and
recover.” In this scheme, some procedure is used
to identify when a deadlock occurs, and then another procedure
is used to deal with the blocked processes. One technique to
identify a deadlock is to maintain a resource graph that identifies
all processes, all resources, and the relationships between them
(that is, which processes exclusively own which resources, and
which processes are blocked waiting for which...

scheduling program in C, please help
1 Objectives This programming project is to simulate a few CPU scheduling policies discussed in the class. You will write a C program to implement a simulator with different scheduling algorithms. The simulator selects a task to run from ready queue based on the scheduling algorithm. Since the project intends to simulate a CPU scheduler, so it does not require any actual process creation or execution. When a task is scheduled, the simulator will...

Decision Making Technology at UPS Regardless of the specific decisions a manager makes, the decision-making process is either programmed or nonprogrammed. Programmed decision making is a routine, virtually automatic process. Programmed decisions are ones that have been made so many times in the past that managers have developed rules or guidelines to be applied when certain situations inevitably occur. In programmed decision making, managers do not need to repeatedly make new judgments about what should be done. They can rely...
