COM

COM is short for Component Object Model, a Microsoft-developed framework for enabling software components to communicate.

It allows objects to be reused across applications, even if written in different programming languages.

COM interfaces are immutable, meaning once defined, they cannot be changed, ensuring backward compatibility.

It relies heavily on reference counting for memory management, which can lead to issues like circular references.

COM also underpins technologies like ActiveX and OLE, and was a precursor to .NET.

The application uses COM to integrate third-party plugins seamlessly.
