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.
Briefly explain the process management in UNIX. UNIX makes use of the easy but powerful process facility that is visible to the user. UNIX follows the model in which the majori
Short term scheduling The short term scheduler as well known as the dispatcher executes most frequently and makes the fine grained decision of which process to execute next. Th
What are the deadlock p revention methodologies? a. Necessitate that processes request all resources before starting - if cannot be granted don't run. b. Process
Define busy waiting and spinlock. When a process is in its significant section, any other process that tries to enter its critical section must loop continuously in the entry c
Contiguous allocation The contiguous-allocation method needs each file to occupy a set of contiguous blocks of the disk. Disk addresses explain a linear ordering on the disk. T
Q. Explain the Concept of Process? A process is sequential program in execution. A process states the basic unit of computation for the computer. Components of process are:
Define the Main reason to encrypt a file Major reason to encrypt a file is secure it for transmission.
Q. What is the use of the command interpreter? Why is it generally separate from the kernel? Answer: It reads commands from the user or else from a file of commands and execu
how fat file system is organised
What is linked allocation, as detailed in text? Directory has pointers to first and last blocks of file. Every block of file (except last) has pointer to the next block.
