I am new to Spring and now a days I hear a lot about Spring Framework. I have two sets of very specific questions:

Set No. 1:

What are annotations in general ?
How does annotations works specifically with Spring framework ?
Can annotations be used outside Spring Framework or are they Framework specific ?

Set No. 2:

What module of Spring Framework is widely used in Industry ?
I think it is Spring MVC but why it is the most used module, if am correct or correct me on this ?

I am newbie to Spring and so feel free to edit this questions to make more sense.
