Can somebody provide insight into buck converters?

Hi friends,
I am not able to understand certain things in buck converters.It s sort of vague.Some basic doubts like,
1) How would be the initial response of the buck converter,like how will the inductor current graph look like before reaching the steady state
2)How exactly the regulation takes place..Like when there is a change in the output voltage how will be the graph of the inductor current.
3)How to design a buck converter in the dis continuous mode..what will be the difference design wise
Thanks in advance
