| The purpose of data is to convey information, provide insights, or support decision-making. | The purpose of a file is to store, manage, and provide access to the data. |
| Data can exist in various formats, such as numbers, text, images, or audio, and can be structured or unstructured. | A file has a specific format and structure, defined by its file type (e.g., .txt, .jpg, .mp3), which determines how the data is stored and retrieved. |
