The role of a package manager

Package managers are programs that we use in Linux to manage packages; that is, to download, install, remove, search, and update packages. Keep in mind that different Linux distributions have different package managers. For example, dpkg, which stands for Debian package manager, is the package manager for Ubuntu and other Debian-based Linux distributions. On the other hand, RedHat-based Linux distributions like Fedora and CentOS use rpm, which stands for RedHat Package Manager. Other Linux distributions like SUSE use zypper as the package manager and so on.
