(mathematics) The set of all possible mathematical entities (points) where a given function is defined.
(mathematics) A ring with no zero divisors; that is, in which no product of nonzero elements is zero.
(mathematics, topology, analysis) An open and connected set in some topology. For example, the interval (0,1) as a subset of the real numbers.
(computing, Internet) Any DNSdomain name, particularly one which has been delegated and has become representative of the delegated domain name and 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; such a region used as a data storage element in a bubble memory

Dealing with complaints isn't really my domain: get in touch with customer services.
His domain is English history.
Some of the most beautiful and thus appealing physical theories, including quantum electrodynamics and quantum gravity, have been dogged for decades by infinities that erupt when theorists try to prod their calculations into new domains. Getting rid of these nagging infinities has probably occupied far more effort than was spent in originating the theories.
Every name in the DNS tree is a domain, even if it is terminal, that is, has no subdomains.
A characteristic of a field. A data domain specifies a data type and applies the minimum and maximum values allowed and other constraints.
