1.5.1.Namespace Introduction

The namespace provides a way to keep one set of names separate from another.
Names declared in one namespace will not conflict with the same names declared in another.
The namespace System is reserved for items in the .NET Framework class library.
The using keyword simply states that the program is using the names in the given namespace.
