The prefix "giga" represents which power of ten?

The prefix "giga" is part of the International System of Units (SI) and is commonly used in various fields, including data measurement in electronics and computing. Specifically, "giga" represents a factor of ten to the ninth power, or 10^9. This means that one gigabyte, for example, is equivalent to 1,000,000,000 bytes. Understanding the significance of this prefix is crucial in fields where measurements and data size are important, as it enables professionals to communicate effectively about large quantities. The other options represent different prefixes: "peta" for 10^15, "mega" for 10^6, and "exa" for 10^18, which can lead to confusion if the correct definition of "giga" is not clearly understood.
