A basic group of natural objects

A collection of DNS or DNS-like domain names consisting of a delegated domain name and all its subdomains.

(computing) A collection of information having to do with a domain, the computers named in the domain, and the network on which the computers named in the domain reside.

(computing) The collection of computers identified by a domain's domain names.

(physics) A small region of a magnetic material with a consistent magnetization direction.

(computing) Such a region used as a data storage element in a bubble memory.

(data processing) A form of technical metadata that represent the type of a data item, its characteristics, name, and usage.

(taxonomy) The highest rank in the classification of organisms, above kingdom; in the three-domain system, one of the taxa Bacteria, Archaea, or Eukaryota.

(biochemistry) A folded section of a protein molecule that has a discrete function; the equivalent section of a chromosome

Dominion; empire; authority.

The territory over which dominion or authority is exerted; the possessions of a sovereign or commonwealth, or the like. Also used figuratively.

Landed property; estate; especially, the land about the mansion house of a lord, and in his immediate occupancy; demesne.

Ownership of land; an estate or patrimony which one has in his own right; absolute proprietorship; paramount or sovereign ownership.

The set of values which the independent variable of a function may take. Contrasted to range, which is the set of values taken by the dependent variable.

A connected set of points, also called a region.

A region within a ferromagnetic material, composed of a number of atoms whose magnetic poles are pointed in the same direction, and which may move together in a coordinated manner when disturbed, as by heating. The direction of polarity of adjacent domains may be different, but may be aligned by a strong external magnetic field.

An address within the internet computer network, which may be a single computer, a network of computers, or one of a number of accounts on a multiuser computer. The domain specifies the location (host computer) to which communications on the internet are directed. Each domain has a corresponding 32-bit number usually represented by four numbers separated by periods, as 128.32.282.56. Each domain may also have an alphabetical name, usually composed of a name plus an extension separated by a period, as worldsoul.org; the alphabetical name is referred to as a domain name.

The three-dimensional structure within an immunoglobulin which is formed by one of the homology regions of a heavy or light chain.

The field of knowledge, expertise, or interest of a person; as, he had a limited domain of discourse; I can't comment on that, it's outside my domain.

A particular environment or walk of life.

People in general; especially a distinctive group of people with some shared interest.

A particular environment or walk of life;

Territory over which rule or control is exercised;

The set of values of the independent variable for which a function is defined

People in general; especially a distinctive group of people with some shared interest;

A knowledge domain that you are interested in or are communicating about;

Domains are defined based on fundamental genetic composition and cellular organization, particularly differences in ribosomal RNA sequences and cell structure.

Archaea and Bacteria are both prokaryotic, but they differ significantly in their genetic makeup and cellular processes.

The three domains of life are Archaea, Bacteria, and Eukarya.

Some kingdoms under the domain Eukarya include Plantae, Animalia, and Fungi.

Cellular complexity is crucial, with domains categorized by the presence of prokaryotic or eukaryotic cells, while kingdoms are further defined by specific organismal characteristics like multicellularity and modes of nutrition.

The introduction of domains provided a higher-level perspective that highlighted the deep evolutionary divergences between major groups of organisms, leading to a reevaluation of relationships within traditional kingdoms.

No, viruses are not included in the domain classification system as they are not considered living organisms due to their lack of cellular structure and reliance on host cells for replication.

Examples include extremophiles, like thermophiles and halophiles, which thrive in extreme environments such as hot springs and salt lakes.

Scientific advancements, particularly in genetics and molecular biology, continue to refine and sometimes redefine the classifications within domains and kingdoms as new information becomes available.

Classifying organisms into domains and kingdoms helps in understanding ecological roles, interactions, and evolutionary relationships, which are essential for studying biodiversity and ecosystem dynamics.

Yes, organisms can be reclassified between kingdoms as new genetic, biochemical, or ecological data becomes available, highlighting the dynamic nature of taxonomy.

This classification system aids in organizing biological diversity into a comprehensible framework, facilitating research by providing a structured way to study evolutionary relationships and educating students on the broad outlines of life's diversity.

A domain is a broader category than a kingdom, encompassing several kingdoms within it based on more fundamental genetic and biochemical characteristics.

It highlights the evolutionary complexity and diversity within Eukarya, encompassing simple single-celled organisms as well as complex multicellular organisms, which indicates significant evolutionary developments within this domain.
