A megabyte is defined as which of the following?

A megabyte is defined as which of the following?

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

Answer: (D)

A megabyte represents about a million bytes. In decimal terms, the prefix mega means 10^6, so a megabyte equals 1,000,000 bytes. Some contexts use a binary approach where a megabyte is 1,048,576 bytes, but that is often called a mebibyte to avoid confusion. The other numbers correspond to different units: 1024 bytes is a kilobyte in binary usage, one billion bytes is a gigabyte in decimal, and one trillion bytes is a terabyte in decimal. So, the one-million-bytes definition matches the common decimal usage for a megabyte.
