Description: A dynamic linker is an essential program in the software runtime environment that is responsible for loading and linking shared libraries to a program at runtime. This allows applications to use code and resources from external libraries without needing to include all the code in the main executable, saving space and facilitating library updates. The dynamic linker is activated when a program starts, identifying the necessary libraries and ensuring they are available in memory. This process not only optimizes resource usage but also allows multiple programs to share the same library, reducing redundancy and improving system efficiency. Additionally, the dynamic linker can resolve dependencies between different libraries, ensuring that all parts of the software function correctly. In most modern operating systems, the dynamic linker is fundamental for performance and application management, as it enables seamless integration of software components and better memory management.
