Domain

Domain is a way of identifying a specific group of computers or websites within a larger structure. It is often used in computer networking to identify a particular system or organizational unit. In addition, the term can also refer to a range of related services such as web hosting, domain name registration, and email.

A domain is typically made up of a number of parts separated by dots, such as example.com. The first part of the domain—the leftmost part—is known as the top-level domain. This can be one of a number of different types, such as .com, .net, .org, or one of a number of country-level domains. The part to the right of the top-level domain—example in the above example—is known as the second-level domain. In some cases, there can be further levels, with each one separated by a dot.

Domain names are typically bought from domain name registrars—these may be the same company as the web hosting service that provides space on a server for a website’s files. Once purchased, the domain name is linked to an IP address—the unique numerical identifier for a computer. This means that any requests for the website are correctly sent to the correct server and the website appears in people’s browsers.

Domain names are an essential part of the internet. They are used to identify both websites and computers, meaning that they are an essential part of navigating the internet and are often the first thing people see when they search for a business or organisation online. As such, they are often one of the most important elements of any online presence and need to be chosen carefully.
