What is Domain Name?
What is Domain Name? – A domain name is the address of your website. People type into the URL bar of their browser to find your website. A domain name is used to find and identify your website. The computer uses the IP address which is a series of numbers. For human beings, it is difficult to remember a number. For this reason, domain names are developed and we can easily browse the website using the domain name instead of using the IP address.
IP address and domain name are unique identifiers, but they are not the same. An IP address is the true identifier of the webserver and the domain name is simply a human-friendly pointer that helps people find the webserver. When you type the domain name in your browser your browser will match the domain name to the IP address. The IP address tells your browser which webserver host the website of the domain name your browser then connects to the web server and requests a copy of your website.
Some examples of Domain names:
Who Manages the Domain Name System?
Internet Corporation For Assigned Names And Numbers (ICANN) manages the domain name system. It is a non-profit organization that creates and implements the policies of the domain name. ICANN give permission to some companies to sell domain name called Domain Name Registrars. Domain Name Registrars are able to sell the domain, manage its records, renewal, and transfer the domain to another registrar.

Working of Domain Name
- When you want to visit a website, you will first enter the domain name in your browser.
- The browser sends this request to a global network of servers that form the Domain Name System.
- These servers search for the name servers that associate with the domain name that you requested.
- The Nameservers are computers that are managed by your hosting company. This computer is known as the webserver
- This web server then fetches the information related to the search of the domain name and sends it to the browser, as a result, the webpage of the domain will appear in your browser.
