These rules are used to establish the priority of the groups attached to the chirality centers and basically based on atomic number.
Geometric Isomerism (Cis, trans) :-
IUPAC- Nomenclature:-
In chemical nomenclature, the IUPAC nomenclature of organic chemistry is a systematic method of naming organic chemical compounds as recommended by the International Union of Pure and Applied Chemistry. It is published in the Nomenclature of Organic Chemistry.

R and S nomenclature of chirality centers:-
The Cahn, Ingold, Prelog priority rules are used for naming chirality centers and geometric isomers i.e., E or Z alkenes.
These rules are used to establish the priority of the groups attached to the chirality centers and basically based on atomic number.
Geometric Isomerism (Cis, trans) :-
The traditional system for naming the geometric isomers of an Alkene, in which the same groups are arranged differently. And these are name as cis or trans. IUPAC has a more complete system for naming Alkene isomers. the R,S system is based on a set of "priority rules", which allow you to rank any groups or atoms.
