If you were to list the components of a typical operating system's kernel, how would you sum up the function of each one?

If you were writing code for a real-time operating system, how would you design it? What type of limitations would you want to impose on the system? Consider the types of scenarios that might lead to unexpected reaction times. There's a chance that a memory access will be slowed down in some manner.

How would you design code for a real-time operating system if you were creating it? What kind of constraints would you want to place on the system? Consider what kinds of situations could result in surprising response times. There is a possibility that a memory access will be hindered in some way.

What sorts of items would you include in the Abstract of your own operating system if you were to design it?
