Final answer:
The Domain Name System (DNS) translates human-friendly domain names into IP addresses that computers use, allowing us to easily access websites without memorizing numerical IPs.
Step-by-step explanation:
The Domain Name System (DNS) enables users to enter a friendly name like www.example.com instead of an address like 192.0.2.1. The DNS is essentially the phonebook of the internet, translating human-friendly domain names into IP addresses that computers understand. Whenever a user types a web address into their browser, the DNS servers are queried to find the corresponding IP address. These servers are distributed across the globe, ensuring redundancy and improved access speed for users around the world. Thanks to DNS, we can easily remember and access millions of websites without memorizing complicated numerical IP addresses.
