3. And while running in the machine, is there a way of knowing?

If you have a heat column rising above your computer then you're running a Prescott (only partly joking).

4. And what is micron and nm??
|
That's the size of the transistor process used to create the chips. Northwoods are 130 nm and Prescotts are 90nm. Usually smaller process technology means faster and cooler but but in the Prescott's case it's more of a mixed bag.
