DNS
The World Wide Web that we know today would have not existed if it was not for the Domain Name System. Every day when you go online and open a website, the Domain Name System is the backend, which helps you see the website you want.
DNS refers to Domain Name System and is a technology for converting domain names to IP addresses. It is the mediator between the IP addresses, the system-side names of the websites and their respective domains, and their user-side alpha-numeric titles. Another important function of the DNS is to control the delivery of email messages.
How does DNS work?
A DNS program works like this - every time a domain name is typed in a browser it is automatically passed on to a DNS server, which translates the name into its corresponding IP address (e.g. the domain name google.com is translated to 74.125.87.147). Thanks to the DNS, we do not need to bother to remember complicated numeric combinations to reach a certain website - we can use its meaningful and much easier to remember domain name instead.
