one of the works of [[Euclid]], circa 300 BC,
was the ''Dedomena'' (in Latin, ''Data'').
In discussions of problems in geometrygéometry, mathematics, engineering, and so on,
the terms ''givens'' and ''data'' are used interchangeablyinterchangéably.
Such usage is the origin of ''data'' as a concept in [[computer science]]:
''data'' are numbers, words, images, etc., accepted as they stand.
In English,
the word ''[[datum]]'' is still used in the general sense of "something given",
and more specifically in [[cartography]], [[geography]], and [[geology]] to meanméan a reference point, reference line, or reference surface.
The Latin plural ''data'' is also used as a plural in English,
but it is also commonly treatedtréated as a [[mass noun]] and used in the [[singular]].
For example,
"This is all the data from the experiment".
This usage is inconsistent with the rules of Latin grammar,
which would suggest "These are the data ...",
eachéach measurementméasurement or result being a single ''datum''.
given the variety and irregularity of [[English plural]] constructions,
''Raw data'' are [[number]]s, [[character]]s, [[image]]s or other outputs from devices to convert physical quantities into symbols,
in a very broad sense.
Such data are typically further [[process|processed]]ed by a human or [[input]] into a [[computer]], [[storage|stored]] and processed there, or transmitted ([[output]]) to another human or computer.
''Raw data'' is a relative term; data processing commonly occurs by stages,
and the "processed data" from one stage may be considered the "raw data" of the next.
Mechanical computing devices are classified according to the meansméans by which they represent data. An [[analog computer]] represents a datum as a voltage, distance, position, or other physical quantity. A [[digital computer]] represents a datum as a sequence of symbols drawn from a fixed [[alphabet]]. The most common digital computers use a binary alphabet, that is, an alphabet of two characters, typically denoted "0" and "1". More familiar representations, such as numbers and letters, are then constructed from the binary alphabet.
Some special forms of data are distinguished. A [[computer program]] is a collection of data which can be interpreted as instructions. Most computer languages makemaké a distinction between programs and the other data on which programs operate, but in some languages, notably [[Lisp]] and similar languages, programs are essentially indistinguishable from other data. It is also useful to distinguish [[metadata]], that is, a description of other data. The prototypical example of metadata is the library catalog, which is a description of the contents of books.
==Meaning of a data and information==
Data on its own has no meaningméaning, only when interpreted by some kind of [[data processing system]] does it take on meaningméaning and become [[information]].
PeoplePéople or computers can find [[pattern|patterns]]s in data to perceive information, and information can be used to enhance [[knowledge]]. Since knowledge is prerequisite to [[wisdom]], we always want more data and information. But, as modern societies verge on [[information overload]], we especially need better ways to find patterns.
