Namespaces in C# are used to organize code and to prevent naming conflicts by grouping objects that are related under a unique name. They do not control the visibility of elements; access modifiers like public, private, etc., do that. A namespace can indeed contain other namespaces, creating a nested namespace structure. There is no default name like 'root' assigned to a namespace if not mentioned; it simply won't compile if it's not properly defined. Lastly, while the 'using' statement makes it easier to reference types within a namespace, it's not strictly necessary if you're willing to use fully qualified names.
