DNS is a distributed system that enables computers to locate and communicate with each other by resolving domain names to IP addresses. The Domain Name System (DNS) is a hierarchical database that maps domain names to IP addresses.

The Domain Name System (DNS) is a hierarchical database that maps domain names to IP addresses. A domain name is a string of characters that identifies a specific site on the Internet. For example, the domain name “www.yahoo.com” represents the website www.

com. When someone types the domain name into a web browser, the browser requests the DNS server for the www.com domain name.

The DNS server responds by returning the IP address for the www.com website. The IP address is a series of numbers that tells the browser where to find the www.

yahoo.com website on the Internet.
