In general, questions of the form "can you help me understand..." might again give you answers which will be of little help of you. A more specific question is always much easier to give a good answer to.

You say that you have read Deedlit's post. What is it exactly that you don't "get"? Do you have trouble understanding some part of the definition? Maybe you don't know what one of the term means or what some symbol represents?

With question as general as yours you will likely end up receiving an answer which says things you already know, possibly phrased differently, and likely not addressing a specific issue you are having.

If you don't know what your issue is, try going through things you understand and ask yourself: what more of this do I want to understand?

(from my own experience asking a correct question often is half of the problem when seeking the answer)
