Internet of Things (IoT) Practice Exam

True or False: CSV, JSON, and XML are tools used to manipulate structured data.

1. True

2. False

3. Partially True

4. Context-dependent

The correct answer is: True

The statement is true because CSV (Comma-Separated Values), JSON (JavaScript Object Notation), and XML (eXtensible Markup Language) are indeed formats commonly used for structuring and organizing data, particularly in applications involving the Internet of Things and data interchange. CSV is a simple format used primarily for storing tabular data in plain text. Each line represents a data record, and fields within records are separated by commas. This straightforward structure makes CSV easy to read and write, allowing for effective manipulation of structured data in spreadsheet applications and databases. JSON is a lightweight data interchange format that uses human-readable text to represent complex data structures. It's widely used in web applications and APIs due to its ease of use and compatibility with various programming languages. JSON handles nested data, which facilitates the representation of structured data in a hierarchical manner. XML is another versatile markup language used to define rules for encoding documents in a format that is both human-readable and machine-readable. It supports complex data structures and enables data validation through schemas, making it suitable for exchanging structured data between systems. These formats serve as tools not just for storing structured data but also for data exchange between different systems, thereby enhancing interoperability—an essential aspect of IoT systems where numerous devices need to communicate
