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.
Explain the ThreadSwitchWithDelay Function used in Netware ThreadSwitchWithDelay( ) This command is used when threads are waiting for an event or resource but don't want t
Give a brief introduction about the operation of your program and show that you understand the idea behind threads and mutual exclusion variable. Why do we need to use mutual exclu
Determine a scheduling policy that is most suitable for a time-shared operating system Round-Robin is a scheduling policy that is most suitable for a time-shared operating s
In fixed portioning scheme, what are the advantages of using unequal- size partitions? With unequal-size partitions there are two probable ways to assign process to partitions.
For reading, most operating systems use demand paging. This means that pages are only read from the disk into physical memory when they are needed. In the page table, there is a re
Q. Advantages and disadvantages of multiprogramming? Advantages 1. High CPU utilization. 2. It appears that many programs are allotted CPU almost concurrently. D
Enhanced Second chance algorithm In this a modify bit is as well used. Now if the ordered pair of reference and modify is (0,0) neither recently used nor modified - the best
Q. Several CPU-scheduling algorithms are parameterized for instance the RR algorithm requires a parameter to indicate the time slice. Multilevel response queues require parameters
Determine the reasons for Poor response time Process busy or High I/O rates or High paging rates
Deadlocks can be detected while the program is running, by running cycle detection algorithms on the graph that de?nes the current use of resources. De?ne this graph as follows:
