The graphical user interface replaced what older system?

The graphical user interface (GUI) replaced the command line interface (CLI), which was the dominant method for interacting with computers prior to the introduction of GUI systems. In a command line interface, users interact with the operating system and software by typing textual commands, which can be efficient for those who are familiar with the commands but can be daunting for inexperienced users.

The GUI offers a more intuitive and user-friendly way of interacting with the computer. It allows users to manipulate graphical elements like windows, icons, and menus with a mouse or touchscreen, making it accessible to a wider audience. This shift from typing commands to using graphical elements significantly lowered the barrier to entry for computer use and provided a more visually engaging experience.

While other interfaces like menu-driven systems do provide some graphical elements, they typically rely on predefined options and are not as versatile or comprehensive as a full GUI. The touch interface, although gaining popularity, is not the direct predecessor of the GUI, and the concept of a graphical command system does not accurately describe the interfaces that existed prior to the widespread adoption of GUIs.
