Question

which of the following units measure millions of bytes of data?
○ a. kilobytes
○ b. terabytes
○ c. gigabytes
○ d. megabytes

Explanation:

To determine which unit measures millions of bytes, we analyze each option:

• Option a: Kilobytes ($\text{KB}$) measure approximately 1000 bytes (or $2^{10}$ bytes), not millions.
• Option b: Terabytes ($\text{TB}$) measure approximately $10^{12}$ bytes (or $2^{40}$ bytes), much larger than millions.
• Option c: Gigabytes ($\text{GB}$) measure approximately $10^{9}$ bytes (or $2^{30}$ bytes), which is billions, not millions.
• Option d: Megabytes ($\text{MB}$) are defined as approximately $10^{6}$ bytes (or $2^{20}$ bytes), which is millions of bytes.

Answer:

d. megabytes
