Freeware is software that is available for use at no monetary cost.

In other words, while freeware may be used without payment it is most often proprietary software, as usually modification, re-distribution or reverse-engineering without the author's permission is prohibited.

Two historic examples of freeware include Skype and Adobe Acrobat Reader.

There is no agreed set of rights or a license or an EULA which would define "freeware" unambiguously; every Freeware publisher defines their own rules for their Freeware.

For instance, redistribution of Freeware by third-parties is often permitted but there is a significant portion of Freeware which prohibits redistribution.

Component Object Model (COM) is a binary-interface standard for software components introduced by Microsoft in 1993.

It is used to enable inter-process communication and dynamic object creation in a large range of programming languages.

COM is the basis for several other Microsoft technologies and frameworks, including OLE, OLE Automation, Browser Helper Object, ActiveX, COM+, DCOM, the Windows shell, DirectX, UMDF and Windows Runtime.

The essence of COM is a language-neutral way of implementing objects that can be used in environments different from the one in which they were created, even across machine boundaries.

For well-authored components, COM allows reuse of objects with no knowledge of their internal implementation, as it forces component implementers to provide well-defined interfaces that are separated from the implementation.

The different allocation semantics of languages are accommodated by making objects responsible for their own creation and destruction through reference-counting.

Type conversion casting between different interfaces of an object is achieved through the method.

The preferred method of "inheritance" within COM is the creation of sub-objects to which method "calls" are delegated.

An image (from) is an artifact that depicts visual perception, for example a two-dimensional picture, that has a similar appearance to some subject—usually a physical object or a person, thus providing a depiction of it.
