- TASK: 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…A program becomes a process when it is an active entity loaded in main memory. max 0 T ↑ What region is used for communication/data sharing between processes? stack sparse address space text data heap no option is correctIs there a difference between "preemptive scheduling" and "preemptive?"

- sleep() is a system call? What are the steps that occur from the time when a call to sleep() is made by a process up to the time that it returns?in C++ please create a Priority : -pre-emptive algorithm code: here are information that will help you Tasks: • Lab 4: Process management • Review Process management algorithms Definitions: (in terms for this lab not formal definitions) • Preemptive: When a new process arrives and has a higher priority than the current running process, Then the current running process is paused and put back in the waiting queue, and the new process starts executing. In most systems it will automatically interrupt the current running job when the new job arrives, however some systems use a predetermined interval (a certain number of time units), to check for new jobs. • Non preemptive: Take no action when a process with higher priority arrives,when a new process with a higher precedence arrives current running process need to finish first before the new process goes Oxford definition: Preempt – to take action in order to prevent (an anticipated event) from happening; forestall. • Metric: a metric is…47. Before proceeding with its execution, each process must acquire all the resources it needs is called a. hold and wait b. No pre-emption c. circular wait d. starvation
