Allocation of Frames
.Minimum Number of Frames
. Defined by computer system architecture
.Maximum number of frames defined by how much physical memory is available to users
.Global Versus Local Allocation
Global replacement – allows a process to select a replacement frame from the set of all frames, even if that frame is currently allocated to some other process; cannot control its own page-fault rate
.Local replacement – requires that each process select from only its own set of allocated frames; more predictable performance
Allows for prioritization
