What is a Domain name?
Your domain name is a key part of your online address, and is what your visitors will use to find you easily. For example, WebServices’s domain name is webservices24x7.com. Your domain name is unique to you; once you have registered it, nobody else can register the same one for as long as you continue to renew it.
Advanced Domain Name Description: A domain name represents a physical point on the Internet — an IP address. The Internet Corporation for Assigned Names and Numbers (ICANN) governs coordination of the links between IP addresses and domain names across the Internet. With this standardized coordination, you can find websites on the Internet by entering domain names instead of IP addresses into your Web browser.
