In discussions of problems in geometrygéometry, mathematics, engineering, and so on,

the terms ''givens'' and ''data'' are used interchangeablyinterchangéably.

and more specifically in [[cartography]], [[geography]], and [[geology]] to meanméan a reference point, reference line, or reference surface.

but it is also commonly treatedtréated as a [[mass noun]] and used in the [[singular]].

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.

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.

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.
