Final answer:
The claim that a gigabyte represents approximately one million memory locations is false; a gigabyte is actually composed of approximately one billion bytes, specifically 1,073,741,824 bytes.
Step-by-step explanation:
The statement that a gigabyte represents approximately one million memory locations is false. In the context of computer memory, a byte is the basic unit and a gigabyte (GB) consists of approximately one billion bytes, not one million. Specifically, one GB equals 1024 megabytes (MB), and each MB is equal to 1024 kilobytes (KB), with each KB comprising 1024 bytes. Therefore, a gigabyte is equal to 1,073,741,824 bytes, which is considerably larger than one million bytes. When discussing units of computer memory, prefixes such as kilo-, mega-, and giga- refer to amounts that correspond roughly to powers of 1024 due to their binary nature, not strictly powers of 10 or one million (10⁶).
