The operating system uses the method of paging for memory management. This method involves various algorithms known as page replacements algorithms that decide which page should be replaced by a new one on demand. A demand is made when the operating system needs a page for processing which is not contained in the main memory. … Read more
FCFS : First Come First Serve is a scheduling algorithm that is used by the CPU to schedule tasks. This algorithm is non-preemptive. In this scheduling algorithm we allocate CPU to the process that comes first in the ready queue. The priority order is decided by the order in which they are requested by the … Read more
The processes in an operating system occupy dedicated memory and the memory is divided into smaller parts called pages. On demand of the CPU, these pages are brought from secondary memory to primary memory and this is done using an algorithm which is discussed elaborately in this article. Paging is primarily used for memory management … Read more
