RPM (Red Hat Package Manager) is a package management system for Linux systems, specifically for Red Hat, Fedora, and other distributions that use the RPM package format. It is used to install, update, and remove software packages on the system.
An RPM package is a self-contained archive file that contains all the necessary files, dependencies, and metadata to install and manage a software application. The package format includes a header that contains information such as the package name, version, and dependencies, as well as the files that make up the package.
RPM uses a database to keep track of installed packages and their dependencies. This allows the system to easily determine which packages are installed, which packages are needed, and which packages can be safely removed.
The main command to work with RPM packages is rpm command. Some examples of using this command are listed below:

Thanks for this wonderful article. One more thing to mention is that a lot of digital cameras arrive equipped with a new zoom lens that allows more or less of your scene to get included through ‘zooming’ in and out. All these changes in the aim length are generally reflected inside the viewfinder and on huge display screen on the back of this camera.
