Differentiate between domain and domain name server and components of DNS

Computer NetworkInternetMCA

The main difference between domain and domain name server (DNS) is that the domain could be a piece of string that helps to spot a specific web site while the DNS (Domain Name System) could be a server that translates the domain to the corresponding ip address to supply the specified webpage.

There are several websites on the globe Wide internet (WWW) as well as education, e-commerce, government, and entertainment sites. It’s necessary for every website to have its own website name. It helps to spot the web site.

The domain is exclusive to a specific user and others cannot use that name for their websites. Once the user enters a website within the browser, the DNS converts that name to the matching ip address to supply the specified webpage.

Definition

Domain is an identification string that defines a realm of administrative autonomy, authority or management at intervals on the web.

DNS or the name System may be a redistributed naming system for computers, services and other resources connected to the web or a personal network.

Usage

The domain helps the user to spot a selected web site whereas the DNS converts the domain names to the numerical science addresses to produce the desired pc services or the devices.

Conclusion

The distinction between domain and DNS is that the domain may be a piece of string that helps to spot a specific web site whereas the DNS may be a server that interprets the domain to the corresponding science address to produce the required webpage.

Components of DNS

The components of DNS are explained below −

Domain Namespace

It is the naming service which is provided by the Internet for Transmission Control Protocol Network / Internet Protocol (TCP / IP). DNS is broken into domains, a logical organization of computers that exist in a large network. All websites are broken into regional sections based on TLD (top-level domain).

Domain Name Server

DNS is the system that's generally used to translate domain and hostnames into the corresponding numeric Internet Protocol (IP) addresses and also to identify and locate computer systems and resources on the web.

When we use an alphanumeric address like "www. tutorials point. com" the computer first needs to understand what numerical value of IP it should contact so as to point out the content.

Name server may be a server liable for keeping the file that contains information about the domain name. Also it contains the corresponding IP addresses for providing the given information during DNS queries. DNS are a fundamental part of the name System.

When you make an invitation for love or money associated with the name, it gets sent to at least one of the name servers. The DNS server now sends back the IP address. This works for the online Site, Mail Servers, and anything supporting the name.

Example of DNS is dns1.registrar-server.com

DNS Resolvers

DNS resolvers are the computers that are used by the ISP's that respond when a user requests to resolve a domain name.
