What can be the causes for the processor to transmission from user mode to kernel mode? Can the user execute arbitrary code after transitioning?
Operating Systems 1. Name three ways in which the processor can transition from user mode to kernel mode? 2. What is a process? What is a thread? 3. Briefly define and explain the following terms. Preemptive scheduling Non-preemptive scheduling
The VAX/ VMS operating system makes use of four processor access modes to facili-tate the protection and sharing of system resources among processes. The accessmode determines:• Instruction execution privileges: What instructions the processor may execute• Memory access privileges: Which locations in virtual memory the current instruc-tion may accessThe four modes are as follows:• Kernel: Executes the kernel of the VMS operating system, which includes memo-ry management, interrupt handling, and I/ O operations• Executive: Executes many of the operating system service...
identify and define the three types of integration strategies. Define and give examples of three intensive strategies
Embedded System.. 1. What is the page table? 2. How to get from Kernel to User and User to Kernel?
how do the user-level threads map to the kernel threads ?
A system provides support for user-level and kernel-level threads. The mapping in this system is one to one (there is a corresponding kernel thread for each user thread). Does a multithreaded process consist of (a) a working set for the entire process or (b) a working set for each thread? Explain WHY thoroughly.
describetwo different types of behaviors and three differentindicators that define the behavior
Define the Pin connected truss. Mention three types of truss?
Given an operating system that supports a one-to-one relationship between user-level threads and kernel-level threads and allows one or more threads from a process to issue blocking system calls while other threads (within that process) continue to run. What must a kernel provide for an effective user-level thread implementation?
