compatibility

Computer
  • 1. Of hardware, the ability of a subsystem (e.g. memory) or an external device (e.g. a terminal) to be substituted for the originally designated equipment. To designate that one manufacturer’s hardware can be connected to another manufacturer’s hardware, the terms plug-to-plug compatible, or plug-compatible, are used. The ability of new hardware to handle interfaces of previous generations is called backward compatibility.

    2. Of software, the ability of a computer to execute directly program code that was compiled, assembled, or written in machine language for another computer. Generally this occurs for successive computers in a given manufacturer’s line. Since later computers are usually more capable (i.e. have a larger instruction set and/or more memory), the ability to run the program of a less capable machine is usually called upward compatibility or backward compatibility. See also portable, emulation.

    3. (of a new piece of software) The ability to reproduce the behaviour of its predecessor, in particular to accept the same input formats.


Logic
  • Describes the relation holding between two statements φ and ψ when neither statement rules out the other, i.e., the statements are cotenable. Early schools of logic considered the notion of entailment to be defined in terms of compatibility or cotenability, so that φψ would be defined as ‘φ is incompatible with the negation of ψ’. Importantly, compatibility between φ and ψ does not entail the related notion of compossibility between the two. If ξ is, e.g., a statement that is necessarily false, that ξ is not possible entails that it is not compossible with any statement, although one may consider ξ to be compatible with itself. The binary connective of fusion has sometimes been interpreted as a compatibility operator.


Geography
  • 1 Being able to accommodate more than one form of activity; for example, ‘to achieve compatible physical and economic coexistence of rural residences, agriculture and cities, through preservation of resources, clustering of development contiguous to cities, buffering uses, and adequate infrastructure’ (Leavenworth County Plan).

    2 To harmonize existing land-use datasets in order to make comparisons within and between countries (Jensen (2006) J. Land Use Sci. 1, 2–4).
