GUI is an acronym for “Interfaz gráfica de usuario“, which means graphical user interface. In simple terms, it is a special kind of interface which allows the user to perform certain actions with the computer or smartphone with the help of visual indicators. For example, to open some program, a person clicks on its icon but does not see any codes.
Programmers “disguise” complicated commands under a beautiful icon after clicking on which the code itself is executed. The graphical interface (GUI) is used in all modern operating systems, be it Android, IOS, Linux, or Windows. This allows anyone to understand the device without learning special programming languages.
Antes, todos los comandos y operaciones con ficheros se realizaban a través de la consola, donde los comandos especiales se introducían en orden secuencial. Saltar de la primera acción a la última no era posible. Gracias a los elementos gráficos (iconos, tablas, diagramas), se puede saltar a la mitad o al final de la operación.
