A domain name is a human-readable address used to access websites and other online resources. It serves as an identifier for a specific location on the internet. Instead of typing a long string of numbers (an IP address), users can enter a domain name into their web browser to reach a website.
For example:
Domain name: www.example.com
IP address: 192.0.2.1 (what the domain translates to behind the scenes)
Components of a Domain Name
1. Second-Level Domain (SLD): The main part of the domain (e.g., example in example.com).
2. Top-Level Domain (TLD): The suffix that follows the SLD (e.g., .com, .org, .net).
3. Subdomain (optional): A prefix that organizes content (e.g., blog.example.com).
How It Works
When you enter a domain name, the Domain Name System (DNS) translates it into an IP address so your browser can locate and display the website.
Example Uses
