What does a gigabyte represent?

• A. 1 billion bytes.
• B. 1 million bytes.
• C. 1024 bytes.
• D. 1 trillion bytes.

Answer: (A)

A gigabyte is a unit of storage used to describe how much data a device can hold. In common labeling, it equals about a billion bytes (10^9). This decimal definition is why “one billion bytes” is the best match for a gigabyte in everyday usage, such as hard drive specs and software reports. There is another, more technical interpretation in computing where a giga is defined as 2^30 bytes, which is 1,073,741,824 bytes. In that binary sense, the term gigabyte is sometimes distinguished as a gibibyte to avoid confusion. To put the other sizes in perspective: one million bytes is a megabyte; 1024 bytes is a kilobyte in binary terms; and one trillion bytes is about a terabyte in decimal terms.
