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 about deadlock prevention? In order for the occurrence of deadlock, the four conditions like mutual exclusion, hold and wait, no pre-emption and circular wait must hap
basic advantage of using interrupt initiated data transfer over transfer under program control without an interrupt
Cold Backup: It is copying the three groups of files when the object is shut down. This is a straight file copy, generally from the storage disk directly to tape. You must end th
approaches to identify free memory area in a heap
Q. What is the purpose of system calls? Answer: System calls permit user-level processes to request services of the operating system.
How does communication takes place in a distributed system? Distributed systems depend on the networking for their functionality. A network is a communication path among two
With software algorithms for mutual exclusion, such as Dekker's algorithm, Peterson's algorithm, or Lamport's bakery algorithm, note that optimizing compilers and out-of-order exec
Explain the Exit (status) Function Exit function causes the calling process to be terminated. Actually, all file descriptors are immediately closed but the process is not
Define CPU scheduling. CPU scheduling is the method of switching the CPU among several processes. CPU scheduling is the basis of multiprogrammed operating systems. By switching
Explain Belady's Anomaly? Also called FIFO anomaly. Usually, on enhancing the number of frames allocated to a process virtual memory, the process implementation is faster, beca
