Is it right to say that paths are represented as URI while web-addresses are represented as URL?

Both URLs and URIs identify resources (which are anything). However, a URL is the term used for an identifier that specifies how to locate the resource Let's consider other kinds of identifiers to help make this clear. An ISBN code identifies a book but does not specify how to find it.

A Dewey Decimal or Library of Congress number also identifies a book and is also used to organize books in a library -- given the number you can find the book on a shelf in the library Getting back to URIs and URLs, a URI that refers to the location or path of a file is by definition a URL NSURL can also be used to parse and manipulate URIs that do not locate resources but merely identify them.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
