Domain is the distinguished part of an abstract or physical space where something exists, is performed, or valid. For example, we may talk about: domain of interest, domain of activity. This concept is used in every branch/sector/field of human activity.
In biology, domain (also superregnum, superkingdom, or empire) is the top-level taxon of organisms in scientific classification, higher than a kingdom. Domain (or its synonyms) is the most inclusive of these biological groupings
In mathematics, a domain of a k-place relation L ⊆ X1 × … × X'k is one of the sets X'j, 1 ≤ j ≤ k
and can define to as:

In mathematics, a domain of a k-place relation L ⊆ X1 × … × X'k is one of the sets X'j, 1 ≤ j ≤ k
and can define to as:
- the domain of a function
- one of the domains of a relation
- an ordered structure studied in domain theory
- a ring-theoretic domain, an integral domain or a Euclidean domain — types of ring
- an open and connected set
- domain of discourse in symbolic logic
In abstract algebra, a domain is a ring with 0 ≠ 1 such that ab = 0 implies that either a = 0 or b = 0 (the zero-product property). That is, it is a nontrivial ring without left or right zero divisors.
But ussualy we know domain as :
The address of a site, without the protocol, path, page or other items attached. For example, microsoft.com is a domain, however, a full URL could be http://www.microsoft.com/stuff/page.html
