Want to add a desktop environment after you install Ubuntu Server?
It can be easily installed.
GNOME stands for GNU Network Object Model Environment.
As the name implies, it is a free and open-source desktop environment for various Linux distributions.
By default, Ubuntu Server does not include a Graphical User Interface (GUI).
A GUI takes up system resources (memory and processor) that are used for server-oriented tasks.
However, certain tasks and applications are more manageable and work better in a GUI environment.
