Why in round robin new processes place at end of queue rather than at beginning?

in roundrobin scheduling each process is gven a fixed time to execute so whenever a new process arrives it is placed at the end of the queue,,,,,the advantage by doing this type of scheduling is response time will be gud...But the disadvantage waiting time is more

What is the need of circular queue in data structures?
Circular queue is a linear data structure that follows the First In First Out principle. A re-buffering problem often occurs for each dequeue operation in a standard queue data structure. This is solved by using a circular queue which joins the front and rear ends of a queue.
What are the Advantages and disadvantages of a queue?
The advantage of multilevel queue scheduling is that it covers all disadvantage of all others scheduling...................... The main disadvantage of multilevel queue scheduling is that it is very difficult to understand and it takes a lot of time........ By waqar ahmad awan (0333-9996376)
What is circular queues Explain in detail along with example?
circular queue
What is queuing machine?
The meaning of a queue machine is a finite state machine with the ability to store and retrieve data from an infinite-memory queue. It is a model of computation equivalent to a turing machine, and therefore it can process any formal language.

How does the scheduler determine which process can run?
A FIFO queue is a list of available processes awaiting execution by the processor. New processes arrive and are placed at the end of the queue. The process at the start of the queue is assigned the processor when it next becomes available and all other processes move up one slot in the queue.
When was A Place in the Queue created?
A Place in the Queue was created in 2005-08.
What is device queue?
The list of processes waiting for a particular I/O device.
What is virtual round robin CPU scheduling?
A variant of round robin scheduling is called selfish round robin scheduling. In selfish round robin, there is a maximum limit on the number of processes that can be placed in the round-robin queue (including the process being executed by the CPU). After that maximum is reached, newly entering processes are placed on a holding queue. Processes in the holding queue do not get any time slice of the CPU. When a process in the round-robin queue completes and leaves the system, the oldest process in the holding queue is allowed to enter the round-robin queue
What is the difference between a priority queue and a circular queue?
A circular queue is similar to the normal queue with the difference that queue is circular queue ; that is pointer rear can point to beginning of the queue when it reaches at the end of the queue. A priority queue is a queue in which each element is inserted or deleted on the basis of their priority. A higher priority element is added first before any lower priority element. If in case priority of two element is same then they are added to the queue on FCFS basis (first come first serve).
What is circular queue operations circular queue?
A circular queue is similar to the normal queue with the difference that queue is circular queue ; that is pointer rear can point to beginning of the queue when it reaches at the end of the queue. Advantage of this type of queue is that empty location let due to deletion of elements using front pointer can again be filled using rear pointer. There are 2 conditions for queue full if queue is implemented using arrays. First condition is Front = 1 and Rear = N Second condition is Front = Rear + 1
What does enqueueing mean?
To 'enqueue' something means to add it to the queue, or a list of to-do processes for, say, a program.

What is the difference between linear and circular queue?
What is the difference between linear and circular queue? In: http://wiki.answers.com/Q/FAQ/2545-37 [Edit categories]The Queue by Default is Linear, it would be termed as Circular if the Last Element of the Queue pointsto the first element of the List
Circular queue in linear data structure?
The queue is a linear data structure where operations of insertion and deletion are performed at separate ends also known as front and rear. Queue is a FIFO structure that is first in first out. A circular queue is similar to the normal queue with the difference that queue is circular queue ; that is pointer rear can point to beginning of the queue when it reaches at the end of the queue. Advantage of this type of queue is that empty location let due to deletion of elements using front pointer can again be filled using rear pointer.
What kind of data structure is required to implement the round-robin scheduling?
cicular queue :D if you want to implement the round robin you need the data structure of circular queue so that when we give the time quantum for the processes then if that process is complete in that time period then its ok but if not then we have to put that process in the queue so that all other processes are also get the time to execute i.e. to remove starvation
What are the various operations that can be performed on a queue?
In queue insertion takes place on rear end and deletion takes place on front end. INSERTION(QUEUE,N,FRONT,REAR,ITEM) :QUEUE is the name of a array on which we are implementing the queue having size N. view comlete ans at http://mcabcanotes.in/algorithm-to-perform-insertion-and-deletion-in-a-queue/
