introduction

In graphical computing, a Desktop Environment (DE) commonly refers to a style of Graphical
User Interface (GUI) that is based on the desktop metaphor which can be seen on most modern
personal computers today. Almost universally adopted in modern computers, these graphical
interfaces are designed to assist the user in easily accessing and configuring (or modifying) the
most important (or frequently accessed) specific OS packed features, yet it is not meant to give
access to the whole vast feature set found in an OS, reason for which the traditional, yet more
complicated and less intuitive, Command-Line Interface (CLI) is still in use when full control
over the OS is required.
A desktop environment typically consists of icons, windows, toolbars, folders, wallpapers, and
desktop widgets.
