Main memory.
The memory subsystem has the only function of accepting memory usage requests and assigning physical memory frames to processes.
We will now describe it's elements:
Currently used algorithm.
Parameters for the currently used algorithm. In this case none.
One of the possible representations.
Available representations on this subsystem.
Click on this button to place the representation on it's own window. This way you can see more than one simultaneously.
Messages telling interesting events.
The menus
Here we will see what the options on each menu mean:
If enabled, the clock will be stopped whenever something interesting happens on this subsystem.
If enabled, this subsystem will pretend that all processes have all their pages; Something like having infinite memory. This is useful to concentrate on other aspects of the system.
