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;

While commonly used in those contexts, realm also refers to broad fields of interest, activity, or conceptual spaces in general discussions.

Yes, domains often imply a level of control, governance, or ownership, whether it's over physical territories, areas of knowledge, or digital spaces.
