Which of the following is an example of structured data?

Structured data refers to information that is organized in a predefined format, making it easily searchable and analyzable by computers. This type of data is typically found in databases and is characterized by its adherence to a fixed schema, which makes it easy to process and query.

Spreadsheets like Excel are prime examples of structured data because they contain rows and columns that adhere to a specific format. Each column can represent a different attribute (such as names, dates, or numerical values), and each row represents a unique record. This organization allows for efficient data manipulation and analytics since the structure is consistent and predictable.

On the other hand, social media posts, audio and video recordings, and handwritten notes are considered unstructured or semi-structured data. These types of data do not follow a strict format, making it challenging to analyze them using traditional data processing techniques. For example, social media posts can vary greatly in content and length, audio and video recordings require specialized tools for analysis, and handwritten notes lack a standardized structure that can be easily interpreted by data processing systems.
