Graininess
Granularity
The condition of existing in grains or granules, referring to the extent to which a material or system is composed of distinguishable pieces. It can either refer to the extent to which a larger entity is subdivided, or the extent to which groups of smaller indistinguishable entities have joined together to become larger distinguishable entities.
Origin
The term derives from the Latin granulum (small grain), but its formal application to information science traces to 1979, when Lotfi A. Zadeh of the University of California, Berkeley published "Fuzzy Sets and Information Granularity," introducing the idea that knowledge could be represented at varying levels of aggregation. Zadeh later coined the phrase granular computing in 1997, establishing it as a formal computing paradigm.
