The id

In computing, an "ID" (or identifier) is a unique label used to distinguish one specific item from all others. Think of it as a name tag or a barcode that helps software and systems recognize and manage individual objects, such as users, files, or database entries, without confusion. IDs ensure accurate referencing and organization within digital systems, enabling efficient retrieval, updates, and interactions. They are essential for maintaining data integrity and ensuring that the right information is accessed or modified.
