Module vs Namespace - Import vs Require Typescript

Question

I am getting lot of confusion with module/namespace/export and import, require, reference usage. Being from Java background, Can someone explain me

Answer 1

1. module is for external packages 2. namespace is for internal packages

Actually the module keyword has been replaced with the namespace keyword.

A better statement is thus Modules are what used to be called external modules, namespace is what used to be called internal modules.
