Features

Red Hat Enterprise Linux includes several administration tools, including a fully graphical administration environment. The default desktop environment is Gnome, but KDE is also available.

Red Hat Enterprise Linux is based on the RPM package management system, the traditional package manager used by Red Hat. It also includes a number of utilities, providing some functions which are not available in the RPM package manager, like automatic dependency resolving.

Red Hat's Linux is one of the preferred distributions when it comes to commercial software availability, partly due to RPM being an important component of the Linux Standard Base specifications. It is also because Red Hat guarantees a certain number of specifications to be met and a strong financial backing, making it a viable platform.
