What is DNS?
Domain Name System (DNS) is a hierarchical and decentralised naming system for computers, like the Internet's phonebook. It includes various information with domain names assigned to each participating entity. When you try to access information online through domain names, like "whoisnote.com", internet browsers interact through Internet Protocol (IP) addresses. DNS interprets such domain names to IP addresses so browsers can gather Internet resources.
How does DNS work?
Every IP address has been assigned to each device on the Internet uniquely, and that address always finds the connected device - like your home street address is used to see you. When t a user types into their web browser (example.com), the device translates it into the machine-friendly address (DNS) to locate the example.com webpage. The DNS process involves converting a hostname (www.example.com) into a computer-friendly IP address (i.e. 192.168.1.1). The process behind the DNS resolution is the different hardware components, so a DNS query must pass. The DNS lookup happened "behind the scenes" and requires no interaction from the user's computer apart from the initial request.
