Domain name server provides this name to the computer or devices which connect to the internet. It consists of a client and a server. Every computer connected to the internet has an ip address assigned to the WiFi card or LAN card. Also the web address has an ip address. For example “google.com” ip address is “18.104.22.168“. Remember computer can understand only the IP address not the name of the website. So, if I hit “gooogle.com” address on the address bar of search engine then DNS server converts google.com to the numeric ip address i.e “22.214.171.124” and sends to your computer.
