What is a domain?

A domain, in the context of the internet, is a unique string of characters that defines a realm of administrative autonomy, authority, or control within the internet. Each website on the internet is identified by a domain name, which serves as its address. When users type a domain into a web browser, they are directed to the corresponding website.

Components of a domain

A domain name is typically composed of two main parts:

1. Top-level domain (TLD): This is the last part of a domain name, such as .com, .org, .net, or country-specific TLDs like .uk or .de.
2. Second-level domain: This is the main part of the domain name that directly precedes the TLD. For example, in the domain name "example.com," "example" is the second-level domain.

Example of a domain

For example, in the domain name "www.google.com," "www" indicates the specific subdomain, "google" is the second-level domain, and ".com" is the top-level domain. Together, they form the complete domain name for the website.

Domains are a fundamental part of the internet infrastructure, enabling users to easily access websites and other online resources.
