Which prefix signifies one million?

• A. Kilo
• B. Mega
• C. Giga
• D. Tera

Answer: (B)

The prefix that signifies one million is "Mega." In the metric system, prefixes are used to denote specific multiples of a base unit. "Mega," derived from the Greek word for "great," is used in various scientific and technical contexts to represent one million (10^6). For example, in computing, a megabyte consists of one million bytes, illustrating how the term is applied in a practical sense. This understanding of "Mega" is essential in various fields, including electronics and telecommunications, where renaming quantities can help in easier management and comprehension of data sizes. While "Kilo" represents one thousand (10^3), "Giga" represents one billion (10^9), and "Tera" signifies one trillion (10^12), recognizing the distinct values of each prefix is crucial in both practical applications and theoretical discussions in the electrical engineering field.
