1. Suggest some mechanism(s) to lower the dispatch latency while scheduling for a real-time system.
Also, discuss any trade-off or consequent constraint associated with it, if any.
2. The Multi-level queue scheduling algorithm suffers from starvation problem. Suggest a solution to it. Further, state that whether starvation could affect the Multi-level feedback queue algorithm. Justify your answers.
3. Differentiate between a thread and a process from the viewpoint of process management.

Problem 1: (a) What are the likely benefits which an organisation may derive from the planning process? (b) Explain the main reasons why an organisation may fail to plan.
Optimal page replacement An optimal page replacement algorithm has the least page fault rate of all algorithms. The algorithm states that a 'replace the page that will not be
Many-to-Many Model The many-to-many model- many user-level threads to many kernel-level threads avoids several of the limitations of the one-to-one model, although extending mu
What is busy waiting? When strict alteration is done there may take place situation like two processes setting their flag as true. Therefore both of the processes have equal pr
Define the Jobs which are admitted to the system for processing is called The Jobs which are admitted to the system for processing is known as long-term scheduling.
Define FIFO Page Replacement Algorithm This policy simply eliminates pages in the order they arrived in the main memory. By using this policy we simply remove a page based upo
4. Describe priority scheduling algorithm. Consider the following set of processes. Show the order in which the algorithm will schedule these processes. Assume preemptive and non-p
