The term gigabyte refers to

  • A.1024 bytes
  • B.1024 kilobytes
  • C.1024 megabytes
  • D.1024 terabytes

Answer: C

Correct answer: 1024 megabytes

The units go up in steps of 1024, which is \(2^{10}\): 1024 bytes to the kilobyte, 1024 kilobytes to the megabyte, and 1024 megabytes to the gigabyte - that is \(2^{30}\) bytes. (Disk manufacturers use powers of ten instead, which is why a “500 GB” drive shows as about 465 GB.)
