* Binomial nomenclature is the system of naming organisms with a two-part name, consisting of the genus and species. For example, *Homo sapiens*.

* The scientific study of how organisms are classified is called taxonomy.

Taxonomy involves:

* Identification: Determining the name and classification of an organism.

* Classification: Arranging organisms into hierarchical groups based on shared characteristics.

* Nomenclature: The system of naming organisms, which includes binomial nomenclature.

So, while binomial nomenclature is a part of taxonomy, it's not the whole field.
