Ok so i just started photography and i need to know a few things.

1. Why are photographs taken in briht sunlight at midday likely to be unsatisfactory.

2. Why is fast film called fast? ( Like is there any reason for it?)

3.Why is a developer temperature of 20degrees celcius ideal?

4. What are f stops? how do the numbers relate to each other in terms on the light they admit to the camera?

I would appreaciate any help here
