Namespaces exist in many languages, including C++ and the Java™ programming language. They came about to help with the organization of large codebases, where oftentimes, there was a concern for overlapping function or class names with the application and the problems that having that would cause. The use of namespaces can help identify what function or utility the code provides, or even help specify its origin. An example of this is the System namespace within C#, which contains all the functions and classes provided by the .NET framework.
