Domain is a term most commonly used in computing and networking that addresses the scope of an administrative authority or control. In other words, it can be used to describe the combination of technical mechanisms, legal ownership and individual views for addressing naming resources and identifiying users in a network.
When referring to the internet, it is a collection of webpages of a particular website, stored on a web server. The user can access the Domain by typing in its unique web address, which is part of the www prefixed domain name like example.com. This each domain is unique, and can include letters, numbers and hyphens separated by a dot for example .com, .gov, and .org.
In an organizational setting, it is a set of user accounts, corporate resources, and any other objects within a specific administrative area. Technically, domains in a more corporate environment can be located within the Active Directory or a Windows NT server Domain.
The Domain Name System (DNS) facilitates translation between domain names and their associated IP addresses, and is the system that directs users to the correct website when typing a web address into their browser.
As an example of Domain usage in the real world, a business with a website usually purchases a Domain which hosts the webpage, allowing customers to access their website by entering this into the address bar of any browser.
By understanding Domain, users can take full advantage of the power of the internet and use Domain to access the internet resources through their chosen web address.
