What is Domain?

A domain is a specific area of focus or expertise. In the context of the internet, a domain is a unique name which identifies a website and its associated resources.

Every website has a unique domain name that serves as its address on the internet. For example, the domain name for Google is “google.com,” and the domain name for Wikipedia is “wikipedia.org.” A domain name consists of two parts: the top-level domain (TLD) and the second-level domain (SLD). The TLD, which may be “.com” or “.org,” is the portion of the domain name that appears after the last dot. The SLD, which may be “google” or “Wikipedia,” is the portion of the domain name that appears before the TLD.

In addition to identifying websites, domain names can also be used to identify email servers, FTP servers, and other internet resources.

Domain name registrars, which are accredited companies that handle domain name allocation and registration, are where domain names are registered. When a domain name is registered, it receives an IP address, which is a number assigned to each and every device connected to a computer network which uses the Internet Protocol for communication. Users can visit the appropriate website or internet resource by using both the IP address and domain name together.

A domain has a domain controller who oversees network security and all fundamental domain operations. So, all user functions, including username/password and shared system resource authentication and access, are managed by a domain. Additionally, a domain is used to provide certain resource capabilities to user accounts, for example.
