What is the degree of a multiprogramming?
The degree of multiprogramming describes the maximum number of processes that a single-processor system can accommodate efficiently. These are some of the factors affecting the degree of multiprogramming: The primary factor is the amount of memory available to be allocated to executing processes.
What does multiprogramming mean?
Definition of multiprogramming : the technique of utilizing several programs concurrently in a single computer system via multiprocessing.
What is degree of multiprogramming Mcq?
The degree of multi-programming is : a. the number of processes executed per unit time.
Who is responsible for degree of multiprogramming?
So, Degree of multi programming is 4. This is maintain by Long term scheduler, because we know that in ready state jobs of maintained in main memory. So degree of multi programming is controlled by Long term scheduler.
How the degree of multiprogramming reduces?
Medium Term Scheduler Medium-term scheduling is a part of swapping. It removes the processes from the memory. It reduces the degree of multiprogramming. This process is called swapping, and the process is said to be swapped out or rolled out.
What is the role of multiprogramming?
The concept of multiprogramming relies on the capability of a computer to store instructions (programs) for long-term use. The goal is to reduce CPU idle time by allowing new jobs to take over the CPU whenever the currently running job needed to wait (e.g. for user I/O).
What is the main objective of multiprogramming?
Answer: The main objective of multiprogramming is to have process running at all times. With this design, CPU utilization is said to be maximized.
Which controls the degree of multiprogramming?
Long Term scheduler
Long Term scheduler mainly controls the degree of Multiprogramming. The purpose of long term scheduler is to choose a perfect mix of IO bound and CPU bound processes among the jobs present in the pool.
What are the types of multiprogramming?
There are mainly two types of multiprogramming operating systems. These are as follows: Multitasking Operating System. Multiuser Operating System.
What is the objective of multiprogramming?
Explanation: The objective of multiprogramming is to increase CPU utilization. Generally, a single process cannot use CPU or I/O at all time, whenever CPU or I/O is available another process can use it. Multiprogramming offers this ability to OS by keeping multiple programs in a ready queue.
