For example, when you visit google.com your browser resolve its IP address for it can open the page for you.
So in a nutshell DNS server do their work by matching a website name to their associated IP address. Let me make it more simple when you type a website name on your browser’s address bar — amateur contacts to the DNS server to look up for the IP address which is associated with the domain name. Then your browser or your computer send safe browsing request to the IP address so it can render the webpage. So probably most of the Internet service providers maintain DNS server which can be slow at a time. Google and open DNS had their own free and maintained public DNS servers that you can use for faster IP resolving. So in order to use either of them DNS server you need to setup them to your computer so the next time your computer use them.
