Question
**Question 13:** If an ad for a computer describes a memory having \( 4 \times 2^{30} \) bytes, how many gigabytes of the computer are uniquely addressable? - **A.** 4GB - **B.** 8GB - **C.** 16GB - **D.** 4MB - **E.** 8MB **Explanation:** This question tests your understanding of binary storage and addressing in computers. The expression \( 2^{30} \) represents one gigabyte (GB) since it equates to 1,073,741,824 bytes. Therefore, \( 4 \times 2^{30} \) bytes are equal to 4 gigabytes. The correct answer is **A. 4GB**.
