Meaning of ‘DNS’

Domain Name System (DNS) is an integral part of the Internet and is often referred to as the backbone of the Internet. It is a distributed database that maps domain names to IP addresses, allowing users to access websites and services by typing in a human-readable address instead of an IP address. The DNS system was created in 1983 by Paul Mockapetris, who proposed the Domain Name System as a way to organize information on the Internet.

The purpose of DNS is to provide resolution between domain names and numerical IP addresses, making it easier for humans to navigate the Internet. Without DNS, web browsers would be unable to locate websites or other resources on the Internet because they need an IP address—not a domain name—to connect. By using DNS, a user can type in a domain name into their browser’s URL bar and have their computer automatically translated into its corresponding IP address so that they can access the requested website or resource.

The structure of DNS is hierarchical, with each level divided by periods (dots). At the highest level are Top Level Domains (TLDs), such as .com, .net, .org, and so on. Beneath these are Second Level Domains (SLDs), which consist of two parts separated by dots and form unique web addresses for example ‘google.com’ or ‘yahoo.com’. Next are Sub domains which appear before SLDs and represent specific sections within larger websites like ‘mail’ in ‘mail.google.com’ or ‘www’ in ‘www.example.com’.

The entire process of mapping domain names to IP addresses takes place through what is known as Domain Name Servers (DNS servers). A DNS server is responsible for resolving requests from web browsers when they try to access websites based on their domain names; it does this by searching through its database and looking up the appropriate IP address associated with each domain name requested by users.

In summary, DNS stands for Domain Name System and it plays an important role in helping users easily navigate around the vastness of cyberspace without having to memorize long strings of digits representing each website’s address on the internet known as an IP address. By utilizing computers known as Domain Name Servers (DNS servers), it allows us humans to use easy-to-remember words instead of complex numbers when accessing our favorite websites online!
