Why is OOP still so widely spread in software?

With OOP being followed by OOA (object-oriented analysis) and OOD (object-oriented design) it soon felt like everything you did in software had to be broken down to objects and their relationshipsto each other. Then the critics arrived on the scene, some of them quite disappointed.

How does the modern operating system support extensibility?

Modern operating systems support extensibility through device drivers and loadable kernel modules. Many modern applications support extensibility through plug-ins, extension languages, applets, etc. The trend of increasing extensibility negatively affects software security.

What is the purpose of extensibility in software design?

Extensibility is a software engineering and systems design principle that provides for future growth.

Why is inheritance not a uniquely OOP feature?

In any case, it is not uniquely a OOP feature and can be done with modules isolating a system function or a set of data and operations on those data within a module. Inheritance. Because objects can be created as subtypes of other objects, they can inherit variables and methods from those objects.
