library vs framework vs architecture

•     A Library is a reusable set of types/functions you can use from a wide variety of applications. The application code initiates communication with the library and invokes it.

    A Framework consists of one or more libraries, but the difference is that Inversion of Control applies. The application registers with the framework (often by implementing one or more interfaces), and the framework calls into the application, which may call back into the framework. A framework often exists to address a particular general-purpose Domain (such as web applications, or workflows, etc.).
    Architecture consists of the guiding principles behind a given application. It is not strongly tied to a particular framework or library.

Frameworks is a collection of classes and tools that help you developing great softwares ... like .net framework or Qt.
Architecture is entirely different : it refers to design pattern or how an application or a framework is organized. What are the modules that compose it and how they communicate together



Architecture is about style, abstract idea, flow, methodology, concept. Framework is something which implements the style, idea, concept etc..or makes it easier to implement it. example,

Architecture: Every component should have standard pluggable interfaces and it should be possible to connect any component to any other.

Framework: Then lego building blocks can be the framework.

Library: some readymade combinations of blocks that would work as the pillars.

Application: A building structure using the pillars and other building blocks(application).
