Resource management by an OS involves:
- Transforming a physical resource into an instance of a virtual resource (e.g., a printer)
- Multiplexing between different instances of a virtual resource when there’s only one physical resource (e.g., use of SPOOLing disk files for virtual printers)
- TDM (time division multiplexing) vs SDM (space division multiplexing); some resources make sense to TDM (printer); others SDM (disk)
- Scheduling resources between programs
