Explanation of boost?

Okay I'm going to get some flaming for this probably. Don't get me wrong, I absolutely am a car enthusiast and love the n54s design.

what I don't get is the concept of boost increase. I know it's measured in psi of course. And i know the n54s stock boost figures roughly.

But how does one 'increase boost'? Is it facilitated by an increase in bolt ons? Such as DPs, FMIC, DCI meth etc? Or how else do you increase boost?

I know you can have boost leaks? Which I presume is by something to do piping being loose letting pressure decrease?

Final question is how do you measure boost? I see everyone saying boost at x psi but how is that measured?

Thanks guys big help if you can answer the above
