In software science, a package management system, or package manager for short, is a set of tools used to install, update, configure, or remove a software package in the operating system. The package manager usually includes a database containing the software package and its dependencies; this information prevents the packets from interfering with each other and provides all the prerequisites for installing a software package. Packages include software, applications, and data. Packages also contain metadata files that contain information such as the name of the software, an explanation of the software's function, version number, manufacturer, check-sum, and a list of software-dependent dependencies. Simultaneously with the installation, the metadata files are stored in the system's local database.Do n't spend too much time searching the internet .
