Connection or dependence, proceeding from the subordination of the parts of a thing to one principle or purpose, as in the parts of a discourse, or of a system of philosophy; a logical and orderly and consistent relation of parts; consecutiveness.
A term frequently applied to caches. If a data item is referenced by a particular processor on a multi-processor system, the data is copied into that processor cache and is updated there if the processor modifies the data. The state that is achieved when both processors' caches always have the latest value for the data is called cache coherency.
