DLL
A DLL (Dynamic Link Library) is a Microsoft Windows file format that contains code, data, and resources that can be used by multiple programs simultaneously. It allows for modular software development by enabling shared libraries, reducing memory usage and disk space through code reuse. DLLs are loaded at runtime, facilitating updates and maintenance without recompiling the entire application.
Developers should learn about DLLs when building Windows applications to create modular, maintainable, and efficient software, as they enable code sharing across programs and reduce redundancy. Use cases include developing plugins, system utilities, or large-scale applications where components need to be updated independently, such as in game mods or enterprise software with shared libraries.
