What is approximately the size of a zettabyte in terms of terabytes?

• A. 1 billion
• B. 1 million
• C. 1 trillion
• D. 1 thousand

Answer: (A)

A zettabyte is equivalent to approximately 1 billion terabytes. The prefix "zetta" represents \(10^{21}\), and "tera" represents \(10^{12}\). When converting zettabytes to terabytes, you divide \(10^{21}\) by \(10^{12}\), which results in \(10^{9}\). This means that one zettabyte is 1 billion terabytes, making the choice of 1 billion the correct answer. Understanding these prefixes helps in grasping the vastness of data sizes in digital contexts.
