A domain name is a unique identifier for a website or other online resource. It consists of a series of letters and numbers, separated by dots, that can be entered into a web browser to access the corresponding website.
For example, in the domain name "example.com", the "example" part is the name of the website or resource, and the ".com" part is the top-level domain (TLD), which indicates that the website is a commercial entity. Domain names are organized hierarchically, with the TLD being the highest level and one or more subdomains being used to identify specific websites or resources within an organization or domain. For example, "www.example.com" is a subdomain of the "example.com" domain, and it could be used to access the main website of the "example.com" domain.
Domain names are a convenient way for users to access websites and other online resources, as they are easy to remember and type into a web browser.
