How many bytes are in a gigabyte?

• A. 1,000 bytes
• B. 1,000,000 bytes
• C. 1,000,000,000 bytes
• D. 100,000,000 bytes

Answer: (C)

A gigabyte is defined as 1,000,000,000 bytes in the context of the International System of Units (SI). This measurement uses the decimal system, which is commonly used for clarity in data storage capacities.

In this case, one gigabyte is equivalent to 1 billion bytes. This is especially relevant in modern computing, where storage devices like hard drives and SSDs often advertise their capacities in gigabytes, reflecting this decimal-based definition.

Understanding this allows individuals to gauge the storage capabilities of devices and perform calculations regarding data storage and transmission effectively. The other choices represent smaller quantities of bytes and do not accurately reflect the size of a gigabyte in this context.
