TAILIEUCHUNG - Lecture Operating System: Chapter 04 - University of Technology

Lecture Operating System: Chapter 04 - Memory management presented basic memory management, swapping, virtual memory, page replacement algorithms, modeling page replacement algorithms, design issues for paging systems, implementation issues, segmentation. | Memory Management Chapter 4 Basic memory management Swapping Virtual memory Page replacement algorithms Modeling page replacement algorithms Design issues for paging systems Implementation issues Segmentation Memory Management Ideally programmers want memory that is large fast non volatile Memory hierarchy small amount of fast, expensive memory – cache some medium-speed, medium price main memory gigabytes of slow, cheap disk storage Memory manager handles the memory hierarchy Basic Memory Management Monoprogramming without Swapping or Paging Three simple ways of organizing memory - an operating system with one user process Multiprogramming with Fixed Partitions Fixed memory partitions separate input queues for each partition single input queue Modeling Multiprogramming CPU utilization as a function of number of processes in memory Degree of multiprogramming Analysis of Multiprogramming System Performance Arrival and work requirements
