How are namespaces determined and connected in the system?

Namespaces are a way to logically divide and organize objects (such as classes, functions, variables) in software systems to avoid name conflicts.

The definition and usage of namespaces depend on the specific technology or programming language, but the general principle is as follows:

• Defining a namespace — declaring a scope with a unique name within which related elements are placed.

• Using a namespace — indicating in the code that elements from a specific namespace should be used, often with keywords like using, import, or a fully qualified name.

For example, in C++:

namespace MyNamespace {
    void func() {}
}

int main() {
    MyNamespace::func(); // call with namespace specified
    using namespace MyNamespace;
    func(); // now it can be called without the prefix
}

In configuration management systems or containers (e.g., Kubernetes), namespaces are used to isolate resources and manage access.

Thus, namespaces help structure code and resources, prevent collisions, and simplify maintenance.
