Final answer:
A measure of computer data storage of approximately 1 million bytes refers to a Megabyte (MB), which is equal to 1024 kilobytes or about one million bytes.
Step-by-step explanation:
A measure of computer data storage of approximately 1 million bytes refers to a Megabyte (MB). One megabyte is equal to 1024 kilobytes (KB), where each kilobyte represents 1024 bytes. Considering that a byte is the basic unit of computer memory, a megabyte essentially consists of about one million bytes (1,024 x 1,024 bytes).
It is important to note that the other options provided in the question, such as a Zip drive, gigabyte, or hard drive, are not units of measurement but rather are devices or larger units of data storage. A gigabyte (GB), for example, is 1024 megabytes, and therefore significantly larger than a megabyte. A hard drive is a device that can store data, and its capacity is often measured in gigabytes or terabytes, whereas a Zip drive is an older storage device format.
