DNS

Introduction

Not everything is as simple and uncomplicated as a naïve person would perceive it to be. Somewhat similar is the case with the computer, as well as the internet network. For an end user, an internet or the computer is the best platform for performing the digital and technological tasks and projects. He is more concerned with the functions these endowments of the modern time would perform, rather than the mechanism that backs up and formulates those functions. Any process or service that the final user acquires, goes through a full fledge, as well as complex digital process and a series of amalgamated networks or digital processes.

DNS

On a broader scale, DNS is an issued naming system based on classification with respect to numerous criteria into successive stages or layers, primarily for the computers, or any particular resource or device linked to any private network, or the internet. Fundamentally, DNS links varying information or data to the domain names allocated to the respective involved or active domains.

In technical terms, the name resolution that is fundamentally attributed to the IP networks or TCP is the Domain Name System, for instance the internet. It is amongst the pivotal functions of the Domain Name System server to host the relevant information, which is pivotal to enable the guest computers to settle conclusively, alphanumeric, and memorable DNS names to the respective IP addresses via which the respective computers communicate with one another.

Moreover, the domain name service interprets the queries or requests in form of the domain names put up by the users, in to the meaningful and appropriate IP addresses, in order to successfully position and situate the devices, as well as the computer services around the world. For a lay man, the connotation that Domain Name System holds is with respect to the function it performs, which is for the internet it acts as a phone book, as it translates the hostnames of the human friendly computers in to their designated and assigned IP addresses. Every command or every request that is put forward by the connected users to the main networks is automatically translated into the assigned IP address, in order to reach from one domain to another (Yih, 2006).

This system, which is the domain name system, makes it feasible for assigning or naming the respective domain names to the assembly of grouping of users and the internet resources in the most appropriate and effective way, regardless of where every entity physically exists or is located.

Caching Only Server

The DNS can be further brought down to numerous categories and other kinds, which perform their respective functions, under the same umbrella, such as the Caching server. Fundamentally, in order to cater to or respond to a certain query brought forward by any human friendly computer, the caching server is designed and developed in a way that it attains the relevant and required information from some other server, which is also known as the Zone Master, and subsequently saves the respective data ...
