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.
