State transition diagram used for operating system management of the Process Control Block has the following states A New (Create)– In this step, process is about to be created but not yet created, it is the program which is present in secondary memory that will be picked up by OS to create the process. Ready -> Ready to run. After creation of a process, the process enters the ready state i.e. the process is loaded into the main memory. The...
2. Consider an operating system that has the fllowing process states, new, ready, waiting (or blocking), running, and terminated. Answer the following questions (a) Draw a process state transition diagram (b) Explain what may cause a process to enter the waiting state from the running state. (c) Do we need a queue for the processes in the running state? Justify your answer (d) Describe the actions taken by a kernel to context-switch between processes 2.

Q.6. Consider a preemptive operating system where processes have priorities and a running process gets preempted (i.e., forced to leave the CPU) as soon as a higher priority process is ready to run. The life cycle of a process, other than the very first process, begins with a "spawn" by another process and ends with either a regular "exit" by the process or a "terminate (process_id)" command by another process of equal or higher priority. COMP 346 – Fall 2019...
During the course of execution, process moves from one state to another state in the state diagram. The only state transition that is initiated by the user process itself is none of the options admit dispatch release Question 4 A scheduler controls the running sequence of processes. The algorithm used by the scheduler is called the scheduling algorithm. Which of the following features is not possible to achieve? Ensuring that each process gets its fair share of the CPU Keeping...
Choose the correct answer 1. A virtual machine executes on a host operating system and a hypervisor provides an API to the actual hardware 2. The guest OS knows that it is not accessing the actual hardware so that it can perform better 3. The VM may supply an environment that is different than the actual host hardware 4. Applications running within the VM have an illusion that they are executing on a real machine Select one: a. All the...
