File Systems

I don't understand file systems. I don't want to love them, just understand them. Here are my questions and the best answers I could find in my path to understanding.

What are the most common file systems in use (particularly in Linux situations)?

What's the difference between mounting, formatting, partitioning?

Describe LVM (logical volume manager) with reference to volumes, volume groups, physical extents, etc.
