FreeBSD Process questions

[Alan Tek]

Hi i'm a Computer Science student at Dalhousie University in Halifax, Nova Scotia, Canada, and i am doing a paper on FreeBSD, and i was wondering if someone could help answer a couple questions on processes for me?  

o        What states do processes move through?

o        How does the OS execute? (within the context of user processes.. as a separate process?)

o       How are new processes created?  Who can create them?

o       What are the most important scheduling criteria for this OS?

o       How does the short-term scheduler select the next process to place in the CPU?  What's the selection function?  What's the decision mode?

o       Is there a single ready queue or multiple ready queues?



Any help would be greatly appreciated, thanks
