DNS (Domain Name System): DNS is a global system that translates human-readable domain names into IP addresses, enabling communication between devices on the internet. How DNS Works: 1. Domain registration: Register a domain name with a registrar. 2. DNS resolution: A DNS resolver translates the domain name into an IP address. 3. IP address lookup: The IP address is used to connect to the desired website or resource. Key DNS Components: 1. DNS servers: Store DNS records and respond to queries. 2
