5 marks | Asked in 2073

Domain Name: There is a massive number of websites available in the WWW. It is necessary to have a domain name to make a website visible to the user.  A domain name is a piece of string that helps to identify a website. For example, the domain of this website is “collegenote.pythonanywhere.com”. The domain name contains an extension to represent the type of the website or the company the website belongs too. The .com refers to a global company while .gov represents a government organization. Similarly, .org represents a non-government organization.

Domain Name System(DNS): Devices and services in the WWW use IP addresses. It is not possible for the users to type each IP address. DNS is the solution to this issue. When the user enters the domain in the web browser, the DNS server converts the domain name to the corresponding IP addresses.

The main difference between domain name and DNS is that the domain name is a piece of string that helps to identify a particular website while the DNS (Domain Name System) is a server that translates the domain to the corresponding IP address to provide the required webpage.
