Round robin scheduling program in java?
Round robin is the scheduling algorithm that is utilized by the CPU, or central processing unit, during the execution of the process. It is specifically designed for time sharing systems.
Explain the lru algorithm from the page replacement algorithm?
First In First Out (FIFO) – This is the simplest page replacement algorithm. ...Optimal Page replacement – In this algorithm, pages are replaced which would not be used for the longest duration of time in the future. ...Least Recently Used – In this algorithm page will be replaced which is least recently used.First In First Out (FIFO) – This is the simplest page replacement algorithm. ...Optimal Page replacement – In this algorithm, pages are replaced which would not be used for the longest duration of time in the future. ...Least Recently Used – In this algorithm page will be replaced which is least recently used.
What is performance measurement in algorithm?
Performance measurement is concerned with obtaining the space and time requirement of a particular algorithm thus quantities depend on the and absence used as well as on computer on which the algorithm is run..........
What is the difference between an algorithm and java code?
In Java programming language, an algorithm refers to a sequence of instructions that have been specified to undertake a particular task within a certain time. An algorithm can take no or several inputs but will generate at least one output.
What is the time complexity of Dijkstra's algorithm?
Dijkstra's original algorithm (published in 1959) has a time-complexity of O(N*N), where N is the number of nodes.
Is the round robin CPU scheduling algorithm suitable for time sharing OS?
Yes, it is one of many scheduling algorithms suitable for time sharing.However it is not suitable for scheduling in a hard realtime OS that must consistently meet deadlines.
What do you mean by scheduling algorithm in OS?
its the algorithm that tells the os what to process next.goes according to :shortest job firstshortest remaining time firstround robin- first in first out system

What is online scheduling and offline scheduling?
Online scheduling is the useage of competitive analysis (or online algorithms) on scheduling problems. Online algorithms is characterized by making decision "online", which means a point in the time axe. In this point of time, we can not see the future jobs or tasks, whereas we only know the jobs or tasks before or at this point of time. In contrast, in offline scheduling problems, there is no the conception of "point of time". We are lords of the world. We stay outside the real world and can see the past and future (jobs or tasks). TThis aspect is called "offline". Since we can see the past and the future, we know the total knowledge of the problem before we make decision (not depending the time). Even use the simpliest method, such as enumeration, then we can obtain the optimal solution. Nontheless, by not knowing the future knowledge of problem, we must make decision. Then we use a critierion to meaure the performance of online algorithm, called competitive ratio. This is a conception like approximation ratio, compering the objective value obtained by online algorithm and that of offline (optimal) algorithm. Offline scheduling is concerned of the classical scheduling problems. Not introducing the conception of "online". Offline scheduling problem is scheduling problem.
Explain with an example first come first serve scheduling algorithm?
By far the simplest CPU-scheduling algorithm is the first-come, first-served (FCFS) scheduling algorithm. With this scheme, the process that requests the CPU first is allocated the CPU first. The implementation of the FCFS policy is easily managed with a FIFO queue. When a process enters the ready queue, its PCB is linked onto the tail of the queue. When the CPU is free, it is allocated to the process at the head of the queue. The running process is then removed from the queue. The code for FCFS scheduling is simple to write and understand. The average waiting time under the FCFS policy, however, is often quite long. Consider the following set of processes that arrive at time 0, with the length of the CPU-burst time given in milliseconds:

Improving security in real time wireless networks through packet scheduling?
In the present network we have not a security of your data so you can do develop a some algorithm,that is useful to protect the packets in dynamically,but now used algorithms can't protect the packets,so we can develop spss algorithm,this algorithm is more protect the packets compare to other algorithms.......
What are the scheduling criteria for CPU scheduling?
CPU Scheduling Criteria: There are many scheduling algorithms and various criteria to judge their performance. Different algorithms may favor different types of processes. Some criteria are. as follows: • CPU utilization: CPU must be as busy as possible in performing different tasks. CPU utilization is more important in real-time system and multi-programmed systems. • Throughput: The number of processes executed in a specified time period is called throughput. The throughput increases .for short processes. It decreases if the size of processes is huge. • Turnaround Time: The amount of time that is needed to execute a process is called turnaround time. It is the actual job time plus the waiting time. • Waiting Time: The amount of time the process has waited is called waiting time. It is the turnaround time minus actual job time. • Response Time: The amount of time between a request is Submitted and the first response is produced is called response time. A CPU scheduling algorithm should try to maximize the following: • CPU utilization • Throughput A CPU scheduling algorithm should try to minimize the following: • Turnaround time • Waiting time • Response time by manish kumar gnit g.noida
What is slack time in project management?
what is slack in project management
Distingui sh between total slack and free slack?
Free slack: The free slack of an activity is the time this activity can be delayed without impact on the following activity. Total slack: The total slack of an activity is the time this activity can be delayed without impact on the finish date of the project.
Why scuba dive at slack tide?
Slack water is the time when there is the least water movement so you don't have to deal with as many strong currents, and this may also be the time when there is the best visibility because there is little water movement to disturb sandy bottoms etc.
What is the advantage and disadvantage of preemptive scheduling algorithm?
The main advantage is that they ensure fairness to all jobs, regardless of its priority and also provide quick response time depending on the CPU time the job needs. The main disadvantage is that it provides indefinite postponement to process.
