GNOME is a very popular desktop environment for Linux systems. This environment has many components. Therefore, this desktop environment is considered "heavy". GNOME is perfect for many mainstream users, but not for old hardware or systems with few resources. People that use GNOME may benefit from understanding some of its components.
