What is a user interface

A user interface (UI) is the means through which a user interacts with a computer or device. It includes the buttons, menus, icons, text fields, and other elements that allow a user to control and interact with the system. The goal of a user interface is to provide an intuitive and user-friendly experience for the user, making it easy to navigate and use the system. A good user interface can improve productivity, efficiency, and overall user satisfaction.
