A label, often referred to as a tag, is a piece of information attached to an object or item that provides details about it. Labels can include names, descriptions, or instructions, helping users identify and understand the purpose of the item. They are commonly used in various contexts, such as in retail, where products have labels displaying prices and ingredients. In the digital world, tags are used to categorize content, making it easier to find and organize information. For example, social media platforms like Instagram and Twitter use tags to group posts by topics, allowing users to discover related content quickly.
