What is DNS?

In modern networking, there are a lot of websites which different names that we keep track of every day. But what if instead, we would have to remember some random numbers in order to visit our favourite websites? That's where a thing called DNS comes in.

What is DNS?

DNS stands for Domain Name System and it is responsible for handling conversion from human-readable domain names to IP addresses, that are understandable for computers (for example www.google.com > 173.194.39.78 and so on). Without DNS, we would have to know the IP address of every website we would like to visit, and while for computers that's not a hard thing to do, for us, it might be quite challenging to remember the IP addresses of every website we've ever visited. DNS is involved every time you try to visit a website.
