DNS stands for Domain Name System, a critical internet protocol translating domain names (like google.com) into IP addresses computers use to connect. Acting like the internet’s phonebook, DNS ensures seamless web navigation. It’s essential for internet functionality, supporting browsing, email, and online services.
