We begin with a brief introduction to memorymanagement systems and then wecompare the memory management systems of reallife operating systems BSD4.4 Windows 2000 andLinux 2.41 IntroductionIn this paper we will be comparing the MemoryManagement (MM) SubSystems of these operatingsystems BSD 4.4 Linux 2.4 and Windows 2000.BSD 4.4 was chosen since it is a representative Unixversion including important operating system designprinciples and today many operating systems likeFreeBSD 3] NetBSD 5] and OpenBSD 6] arebased on it. Moreover it is very well documentedin 12]. Windows 2000 was chosen since it is a verypopular operating system for use as a desktop especially with beginners and has now evolved into a mature operating system. Linux 4] 2.4 was chosen because it is growingmore and morepopular by the dayand seems to have an important place in the future.We will not be much interested in the performancecharacteristics of these systems in this paper insteadour focus will be on their design and architecture.2 Memory Management SystemsThe Memory Management System is one of the important core parts of an operating system. Its basicfunction is to manage the memory hierarchy of RAMand hard disks available on a machine. Its importanttasks include allocation and deallocation of memory1Page 2to processes taking care of logisticsand implementation of Virtual Memory by utilizing hard disk as extraRAM. The Memory system should be optimized asfar as possible since its performance greatly affectsthe overall performance and speed of the system.2.1 Virtual MemoryAn important concept in the context of MM Systemsis Virtual Memory.
