How is process management done in multiprocessing systems?
There are two accost for the process management in multiprocessor systems.
In master-slave configuration one of the processor units is identified as the master processor, which implements the OS routines and performs all control functions in the system. So the master processor decides which process to execute on which processor. All other processors are slaves to the master they basically perform the tasks detailed to them by the master. The disadvantages and advantages of the master-slave configuration are:
In symmetrical multiprocessors, a processor is identical in their ability to perform control functions. A processor selection is stimulated whenever an interrupt is raised in the system. The chosen processor handles the interrupt. The remaining of the system can continue its operation. This provides improved reliability than master-slave configuration. A disadvantage of the system is that it doesn't fully exploit the potential of multiple processors in the system.
What is page fault and what are the steps taken by the OS to remove page fault? A page fault is caused while a page that hasn't been brought into memory is being addressed. The
Synchronization serves two purposes: 1) to ensure safety for updates on shared data (e.g. to avoid races conditions), and 2) to coordinate and order actions taken by threads (e.g.
what branch of goverment were the federal courts are?
A daemon is a process that removes itself from the terminal and disconnected, executes, in the background, waiting for requests and responding to them. It may also be described as
Assume that P A , P B and P C are three distinguished program s . When P A is executed, it needs 10 ticks to complete its execution and it forks new processes executing P B at tick
TII stands for The abbreviation of TII is Table of incomplete instructions.
Q. Explain a mechanism by which one segment could belong to the address space of two different processes. Answer: Because segment tables are a collection of base-limit register
Suppose your process starts up, and allocates some memory with malloc(). The allocator will then give part of a memory page to your process. The OS then updates the corresponding p
Explain Process scheduling Process scheduling consists of the subsequent sub-functions: 1. Scheduling : Selects the process to be implement next on the CPU 2. D
