User Interface (UI) is the interface through which people interact with a computer system. It encompasses all the visuals, such as buttons, menus, windows, icons, and other visual elements. It provides an easy way for people to interact with a system by allowing users to give commands or view information. UI design is a critical part of software development, as it governs how users interact with the system and can make or break the user experience.User Interface (UI) is the interface through which people interact with a computer system.
