The document discusses namespaces in C# and how they help organize code. It begins by explaining that Console is a class in the System namespace, so Console.WriteLine refers to the WriteLine method of the Console class. It then discusses how namespaces help avoid naming collisions and allow logical grouping of classes. Key points include: - Namespaces are used to logically group related classes and avoid name clashes - Classes can be organized into hierarchical namespaces (e.g. namespace1.namespace2.Class) - The using directive allows omitting namespaces when referring to classes - Classes provide useful functions, so related functions are grouped into classes within namespaces
