Dynamic Library
A dynamic library (also called shared library) is a collection of compiled code and data that can be loaded and linked at runtime by multiple programs simultaneously. It enables code reuse, reduces memory usage, and allows for updates without recompiling dependent applications. Dynamic libraries are a fundamental component of modular software architecture in modern operating systems.
Developers should use dynamic libraries when building modular applications that need to share common functionality across multiple programs, as they reduce executable size and memory footprint. They are essential for creating plugin systems, enabling hot updates without restarting applications, and maintaining backward compatibility in software ecosystems. Dynamic libraries are particularly valuable in large-scale systems where code reuse and efficient resource management are critical.
