Microsoft's implementation of the shared library concept in Windows and OS/2
via Wikipedia infobox
A dynamic-link library (DLL) is a shared library in the Microsoft Windows or OS/2 operating system. A DLL can contain executable code (functions), data, and resources.
A DLL file often has file extension .dll even though this is not required. The extension is sometimes used to describe the content of the file. For example, .ocx is a common extension for an ActiveX control and .drv for a legacy (16-bit) device driver.
