Tabs are small, clickable elements found in software applications and web browsers that help organize content. They allow users to switch between different sections or pages without losing their place. For example, in a web browser like Google Chrome, tabs enable users to open multiple websites simultaneously, making it easy to navigate between them. In applications like Microsoft Excel, tabs can represent different sheets within a workbook. Each tab can contain unique data or information, allowing users to manage and access various datasets efficiently. This organization helps streamline workflows and enhances user experience by keeping related content grouped together.
