Techopedia explains Desktop
As personal computers evolved from operating systems based on command line to more advanced GUI designs, the desktop remained a common concept in design. Users can change the background image of a desktop, customize icons, or otherwise arrange the desktop into what most appeals to them in terms of aesthetics and function.
New innovations in desktop design include desktop virtualization and desktop-as-a-service, where remote control of the desktop may be part of a provided tech service. This type of remotely provided interface works with cloud services, where more of the computer’s programming and file supply resides in a safe external location.
