About the telephoto and wide angle stuff for camera lens,
A simple way to imagine how it is like is to do a L and 7 with your hand. Join both hand up and for a small rectangle box. This is your screen. Start by placing the screen near to your eye and move them far and near to you. What you see through the screen when far away from you is a telephoto view and what you see near to you is a wide angle view.
The point and shoot mostly have the mm numbers written on the lens if I am not wrong. But for layman explaination, it is easier to explain by microscope values of X maginfication. But it doesn't actually explain how wide your lens can capture as it just mention that it can capture 3 time more tele the widest view when your camera is at 3X.
20mm, 3X = 60mm
10mm, 3X = 30mm
Don't worry about the full frame stuff as it should be for more advance users. Learn the basics of operating your camera and the structure different of a DSLR vs a PNS first ba, there are stuff like hyperfocal and how light theory like defraction for you to learn before advancing. Hope it is easy to understand as my english isn't that good and I am poor in conveying ideas across.
