A domain name is said to be a representation of a website address on the internet. The definition of a domain name is the name of a computer on the internet that usually corresponds to an IP address and serves as an easy and unique identification label for your website. The domain name is that part of the Uniform Resource Locator (URL) that tells a server where and whether to forward a request for the website using the domain name system (DNS). In simple terms, it is a website’s address. It locates an organization or a person on the internet using this web address, like a sign post that points out your location on a map.
Technically, a domain name (Web address or URL) is an addressing construct used for identifying and locating computers on the Internet. While computers use Internet Protocol (IP) numbers to locate each other on the Internet, people find them hard to remember. Therefore, domain names (Web addresses) were developed to permit the use of easily remembered words and phrases to identify Internet addresses.
Domain names are usually comprised of three parts, separated by dots in between – the “www”, the chosen name, then the suffix or what is called the Top Level Domain (TLD) extensions that reflects the purpose or physical location of your website. When you type in a domain name, it can be in this format: www.nameofwebsite.com.
The WWW, often verbalized as "dub-dub-dub," is a mnemonic commonly used for the host name of the company's Web server for uniformity over the Web. If there are multiple Web servers, it is actually the host name of the server that balances the workload and distributes the query to the next available Web server.
The domain names are registered with any of several dozen registrars. To find out if a domain name is taken, two popular domain name registrars are Network solutions (www.networksolutions.com) and Go Daddy (www.godaddy.com)
Domain Extensions (TLD’s)

Domain registration is to register a domain name in the domain name "registry", a directory of all the domain names and their corresponding computers on the Internet. An Internet Domain name Registry is an entity that receives domain name system (DNS) information from domain name Registrars. The Registry creates and maintains the database of domain names for a given top-level domain (e.g. .BIZ, .INFO, .COM).
Rules for registration of .biz, .com, .info, .name, .net and .org names
The .com, .info, .net, and .org TLDs are open and unrestricted global domains meaning that anyone in any country can register them for any purpose. Traditionally, however, domain names in .net have been used by organizations involved in Internet infrastructure activities and .org is frequently used by noncommercial organizations. .Biz is a restricted domain and reserved solely for business use. Likewise, .name is dedicated exclusively to individuals' personal names. In general domain names cannot have more than 63 characters excluding the "www" and "extension."
