Input types refer to the various ways users can provide data to a system or application. Common input types include text fields, checkboxes, radio buttons, and dropdown menus. Each type serves a specific purpose, allowing users to enter information in a way that is easy and efficient. For example, a checkbox allows users to select multiple options, while a radio button restricts them to a single choice. Different input types enhance user experience by making forms and interfaces more intuitive. By using appropriate input types, developers can guide users in providing the necessary information without confusion. This improves data accuracy and streamlines the overall interaction with the application.
