Domain Name

What Is a 'Domain Name'?

Domain Name System, or DNS, is the most recognized system for assigning addresses to Internet web servers (aka "Internet hosts"). Somewhat like international phone numbers, the domain name system helps to give every Internet server a memorable and easy-to-spell address. Simultaneously, the domain names keep the really technical IP address invisible for most viewers.

How Domain Names Are Spelled

1) Domain names are organized right to left, with general descriptors to the right, and specific descriptors to the left. It is like family surnames to the right, specific person names to the left. These descriptors are called "domains".

2) The "top level domains" (TLD, or parent domain) is to the far right of a domain name. Mid level domains (children and grandchildren) are in the middle. The machine name, often "www", is to the far left.

3) Levels of domains are separated by periods ("dots"). 

• Example 1 above) About is the mid-level domain, .com is the top level domain.
  
  
• Example 7 above) japantimes is the smaller mid-level domain. .co is the larger mid-level domain. .jp is the top level domain. 
  
  
• Example 10 above) spain is the mid-level domain, .info is the top level domain. 
  
  

Tech Trivia Note: Most American servers use three-letter top level domains (e.g. ".com", ".edu"). Countries other than the USA commonly use two letters, or combinations of two letters (e.g. ".au", ".ca", ".co.jp"). 

A Domain Name is Not the Same as URL

To be technically correct, a domain name is commonly part of a larger Internet address called a "URL". A URL goes into much more detail than domain name, providing much more information, including the specific page address, folder name, machine name, and protocol language.

A Domain Name is Not the Same as IP Address

In the end, a domain name is intended to be a friendly and memorable "nickname" only. The true technical address of a web host is its Internet Protocol Address, or IP Address. 

Web Hosting Services Delhi

A web hosting service is a type of Internet hosting service that allows individuals and organizations to make their website accessible via the World Wide Web. Web hosts are companies that provide space on a server owned or leased for use by clients, as well as providing Internet connectivity, typically in a data center. Web hosts can also provide data center space and connectivity to the Internet for other servers located in their data center, called colocation, also known as Housing in Latin America or France.

The scope of web hosting services varies greatly. The most basic is web page and small-scale file hosting, where files can be uploaded via File Transfer Protocol (FTP) or a Web interface. The files are usually delivered to the Web "as is" or with minimal processing.[1] Many Internet service providers (ISPs) offer this service free to subscribers. Individuals and organizations may also obtain Web page hosting from alternative service providers. Personal web site hosting is typically free, advertisement-sponsored, or inexpensive. Business web site hosting often has a higher expense.

Single page hosting is generally sufficient for personal web pages. A complex site calls for a more comprehensive package that provides database support and application development platforms (e.g. PHP, Java, Ruby on Rails, ColdFusion, or ASP.NET). These facilities allow customers to write or install scripts for applications like forums and content management. Also, Secure Sockets Layer (SSL) is typically used for e-commerce.

The host may also provide an interface or control panel for managing the Web server and installing scripts, as well as other modules and service applications like e-mail. Some hosts specialize in certain software or services (e.g. e-commerce), which are commonly used by larger companies that outsource network infrastructure.
