The word data means "known facts". Data especially refers to numbers, but can mean words, sounds, and images. Metadata is data about data. It is used to find data.

Technically, data is a plural word: but the singular datum is rarely used. So data often gets used as if it were a singular word. But we say "data are", not "data is".

'Data' is also used in the name of some characters:

  • Data (Star Trek), a fictional android in the television series Star Trek: The Next Generation
  • Data, a character in the movie The Goonies, played by actor Ke Huy Quan
