Fill in the missing units of data, using the list given: • byte • gigabyte (GB) • megabyte (MB) • nibble The units of data increase in size from smallest to largest. Smallest bit ……………………………………………….. kilobyte (kB) ……………………………………………….. ……………………………………………….. Largest terabyte (TB) [4] 2 (a) Nancy uses her camera to capture images of her holiday.
