- When the parent process terminates, whether normally or unexpectedly, so do the offspring processes.A deadlock occurs when two or more processes wait an excessive amount of time for a shared resource that belongs to another process, and another event waits for an event that is triggered by another.Main Memory (MM) and Central Processing Unit are important resources of the computer system that must be carefully managed. The part of Operating System (OS) that manages the memory is called Memory Manager. 'Partition' is a memory management scheme, which allocates processes in MM into a unique fixed-size partition; each partition contains exactly one process. When a partition is free, the OS selects a process from the input queue and loads it into the free partition; when the process terminates, the partition becomes available; a free partition is called 'hole'. Please, reply to the following questions by giving your own ORIGINAL and UNIQUE answers: a) Draw a picture of the Main Memory (MM) divided into A 'assigned partitions' and B 'holes': fix your values for A and B1, and draw the corresponding MM layout. In the following, Pi, Pj and Pk are three processes residing in MM b) Considering the 7 states diagram, answer to the following questions: 1) Can Pi be in the 'New' state? Why?…
- All deadlocks are caused by competing demands for resources.When a deadlock has been identified, the requested resources are made available to those who are unable to go forward.As a consequence of the mechanism that detects deadlocks, those who have reached a standstill are given access to the resources that are accessible to them.
- Real Time Scheduling: Select all statements below that are true EDF scheduling assigns the highest priority to a process with the smallest remaining time until its deadline. RM scheduling assigns a higher priority to processes with shorter periods. Rate Monotonic (RM) scheduling works by dividing the total amount of time available into an equal number of shares, and then each process must request a certain share of the total when it tries to start. If a process has period p, it is activated every p units of time. A real-time system is schedulable under Earliest Deadline First (EDF) when its overall CPU utilization is less than or equal to 1. A real-time system is schedulable under RM when its overall CPU utilization is less than 1.TASK1: DESCRIPTION One of the simplest methods for memory allocation is to divide memory into several fixed-sized partitions. Each partition may contain exactly one process. In this multiple-partition method, when a partition is free, a process is selected from the input queue and is loaded into the free partition. When the process terminates, the partition becomes available for another process. The operating system keeps a table indicating which parts of memory are available and which are occupied. Finally, when a process arrives and needs memory, a memory section large enough for this process is provided. When it is time to load or swap a process into main memory, and if there is more than one free block of memory of sufficient size, then the operating system must decide which free block to allocate. Best-fit strategy chooses the block that is closest in size to the request. First-fit chooses the first available block that is large enough. Worst-fit chooses the largest available…When a deadlock is identified, the requested resources are made available to those who cannot proceed.
