What is a domain?
Domain is the URL of a website and you can find it on the top of your browser window in the URL bar? It’s the part that starts with “http://” in the address bar. The second part of the URL is the domain. In our case, it’s www.thewebvibe.com.
How domains work?
Every website is identified by an IP address. This numeric set is what your computer uses to connect to the server where the website data lives.
Numbers are great for a computer, but it’s easier for people to use words they can remember. The words used to identify a website are known as the domain or URL, and like the IP address, they’re unique to each website. Domains are connected to IP addresses.
If you have a great idea for domain name i think you should register it right away otherwise there is risk that some one else register the same domain. As a matter of fact you can earn money on your domain name. Buy a potential good domain name and list it for sale.
