It contains pages that are in the main memory which the size of the working set will be altered accordingly. Windows paging system uses a working set concept, which is determined by amount of memory assigned in the current process. It will also bring one through eight pages in memory simultaneously instead of bringing them one by one. Windows uses cluster demand paging, which pages are brought in the memory when they are needed. Page replacement decides which memory pages to page out when a page of memory needs to be allocated. While Linux can also access 4GB of physical memory the difference is the upper part is allocated with 1GB of memory for kernel-mode, while the lower part is allocated with 1GB for user-mode.Īn important part in any memory management system is the page replacement system. The upper part of the address space is allocated with 2GB of memory for windows kernel-mode, while the lower part is also allocated with 2GB of memory for user-mode.
