Assignment description: When an operating system has been running for a while without reboot, and more it keeps allocating and de- allocating pages, the quicker the memory becomes fragmented. And the kernel may not always be able to defragment enough memory for a requested size on time. If that happens, applications may not be able to allocate larger contiguous chunks of memory even though there is enough free memory available. Being a system admin and considering the following scenario, discuss the current proposed solutions to solve the problem caused in this case and critically analyze the performance of the proposed solutions to solve the problem. Provide a report considering the following outlines. Scenario: In the following snapshot of running operating system, we can see that there is a free memory space equal to (55 KB). Assume that new process (process#07) needs to be run inside the memory and required 50 KB but the memory (fragment) is not contiguous. Assigned Space Assigned…
Basic deadlock questions: Select all of the following statements that are true. Reusable resources are produced and consumed dynamically. Interrupts, messages, and signals are examples of consumable resources. A deadlock means that at least two processes cannot continue working because they are waiting for each other. In order for a deadlock to occur only one of the four introduced deadlock conditions must apply. One of the four introduced deadlock conditions is non-preemption. A set of processes is in a safe state S if S is not a deadlock state and any state T reachable from S is not a deadlock state.

Which of the following are true with respect to a mutiprogrammed, time-shared (multi-tasking) environments? (Select all that apply.) Context-switching provides optimal use of the CPU by scheduling ready processes as soon as the CPU is available. Context switching is a zero cost operation. There is better performance when the multiprogramming level is very low. Critical sections and race conditions are a direct result of context switching and programs sharing memory.
