Domain vs. Region — What's the Difference?

An area of territory owned or controlled by a particular ruler or government

In geography, regions are areas that are broadly divided by physical characteristics (physical geography), human impact characteristics (human geography), and the interaction of humanity and the environment (environmental geography). Geographic regions and sub-regions are mostly described by their imprecisely defined, and sometimes transitory boundaries, except in human geography, where jurisdiction areas such as national borders are defined in law.

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.

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.
