DNS stands for “Domain Name System“. You can think of it as the phonebook of the Internet. When a computer (for example your laptop) connects to another computer (for example a server that hosts a website) over the internet in order to gather information, they do so by connecting via the Internet Protocol. Each computer has an IP address, just like phone numbers, so they know which device to connect to. Since remembering a bunch of numbers for each use case is not the most user friendly way to surf the web, humans invented DNS so they can type in actual words that are easier to remember than long lines of numbers. That way, you can visit our website by typing in www.iode.tech, instead of typing numbers into your browser.
