DNS, or Domain Name System, plays a crucial role in making the internet easy to use. Here’s how:
Imagine DNS as a giant phone book for the internet. When you type a website name (like http://www.example.com) into your browser, DNS translates that human-readable name into the numerical IP address that computers use to identify each other (like 192.0.2.1).
Without DNS, you’d have to remember complex number sequences for every website you want to visit. DNS does this translation quickly and automatically, allowing you to use simple names instead.
DNS also helps distribute internet traffic by allowing multiple IP addresses for popular websites. This lets users connect to servers that are closer or less busy, improving speed and reliability.
In essence, DNS acts as a bridge between how humans prefer to navigate the internet and how computers actually communicate, making the whole system work smoothly for users.
