Dynamic Link Library – DLL

A Dynamic Link Library (DLL) is a type of file that contains code and data that multiple programs can use simultaneously. DLLs are designed to promote code reuse, efficiency, and modular programming.

They are commonly used in Windows-based systems to support shared functions such as graphics rendering, device communication, and user interface controls. Instead of including all necessary code in each program, developers can rely on DLLs to provide standardized functionality across applications. This structure helps keep program sizes small and simplifies software updates by allowing DLLs to be modified independently.
