ordering
[OED]: The action of ORDER v. (3. gen. A rank, row, or series; 4. a. Math. The degree of complexity of an analytical or geometrical form, equation, expression, operator, etc., as denoted by an ordinal or cardinal number (e.g. the number of differentiations required to reach the highest derivative in a differential equation))
A sequence (or series) of discrete categories or components that vary according to some algorithm, criterion or rule. An ordered array is systematic,not random or chaotic. Information is generated, transmitted and recorded in ordered patterns, i.e. it ‘makes sense’ versus non-sense. For example the sequence of purine and pyrimidine base in a sample DNA carries the information for the construction, operation and maintenance of an organism.
