What is User Interface (UI)?
A type of interface that allows users to control a software application or hardware device. A good user interface provides a user-friendly experience by allowing the user to interact with the software or hardware in an intuitive way. It includes a menu bar, toolbar, windows, buttons, etc.
Example
Consider a mobile weather app. Its user interface includes elements such as buttons, icons, menus, and navigation bars that allow users to view weather forecasts, check current conditions, and access additional features. The UI design ensures that information is presented clearly, with intuitive controls for users to interact with the app effortlessly. For instance, users can swipe to navigate between different sections, tap on icons to access detailed forecasts, and use dropdown menus to select specific locations. A well-designed UI enhances usability and makes the weather app intuitive and enjoyable to use.
