Description: Module dependency refers to an essential requirement for a software module to function correctly within a system, such as an operating system or application environment. In the context of programming and system administration, a module can be a library, a package, or a component that provides specific functionalities. Dependency implies that the module in question needs other modules or libraries to operate effectively. Without these dependencies, the module may fail to execute or may not offer all its functionalities. Dependency management is crucial in development and production environments, as it ensures that all necessary components are present and up to date. In various systems, package management and dependencies are handled through tools that allow administrators to install, update, and remove packages efficiently, ensuring that all dependencies are resolved automatically. This not only facilitates software installation but also helps maintain the overall stability and security of the system.
