The term 'Computer Desktop Symbol' refers to an ICON, which is a small graphical representation of a program, file, or command. Icons are typically used in computer operating systems to provide a visual representation of the program or file that can be clicked on to open it. They are also used to represent commands, such as the 'trash can' ICON for deleting files. Icons are usually located on the desktop of a computer and can be customized by the user.
