What is User Interface (UI)?

User Interface (UI) refers to the visual and interactive elements of a software application or system that enable users to interact with it. It includes graphical elements such as buttons, menus, forms, and other visual components, as well as navigational elements and interactive features that facilitate user interaction and engagement. The UI design focuses on creating an intuitive and user-friendly interface that allows users to easily navigate, access information, and perform actions within the software application. A well-designed UI enhances the user experience and contributes to the overall usability and effectiveness of the system.
