Q. What is Domain explain?

Domain can be an apartment complex, a town or even a country. Sub-domains can correspond to organizations like expertsmind. United States comes under a large domain. "US". Computers known as name servers contain database of Internets host addresses. They translate word addresses or persons understandable into numeric equivalents. Let's see another instance of Internet address:

https://www.expertsmind.com

What does it all mean? Actually to ISP server, very little. Server wants to see something quite different. It wants to see a 32-bit number as an Internet address. Something like this equivalent decimal grouping:

198.168.45.249

Internet addresses, known as universal resources locators (URL), are translated from one form to other using an address resolution protocol. First address is in the form we are most used to and that user use to access an Internet site. In this illustration, address is for a website, identified by hypertext transfer protocol (http) that controls access to web pages. Following http is a delimiter sequence, ://, and identification for world wide web (www).

Domain name, expertsmind.ac follows www and identifies general site for web.(dot) edu is one instance of a domain top, which is a broad classification of web users. Other common domain tops are:

.com for commerce and businesses

 .gov for government agencies

 .mil for military sites

 .org for all kinds of organizations.

Finally, in this illustration is a country code, again preceded by a dot. Here we are using us for United States, which is default country.

Addresses can be followed by subdomains separated by slashes (/) or dots as needed. These addresses are translated into a 32-bit (4 decimal numeric groups) address demonstrated for https:// www.expertsmind.us.
