DNS (Domain Name System) is a centralized database that translates human-readable domain names, like "google.com" or "youtube.com", into unique IP addresses, which computers use to communicate with each other on the internet.
An IP address is like an address book that tells a computer where to find a specific location on the internet, like a house's address book telling a car where to park.
DNS works by dividing a domain name into smaller parts, called domains, separated by periods (.). For example, "google.com" would be broken down into "google", "com", and ".com".
Each part of the domain name points to a specific address in the DNS database, which contains information about that domain's owner, the server responsible for handling requests, and the type of services offered.
When you visit a website, your computer sends a DNS request to a DNS server, asking for the IP address of the website's server. The DNS server translates the domain name into an IP address and then sends the response back to your computer.
This way, your computer can communicate with the website's server and access the website's content
