Definition of domain name system 

The domain name system (DNS) is a system that translates human-readable domain names into IP addresses, facilitating the identification and location of devices on the internet.

Explanation of domain name system 

DNS acts as a decentralized directory that converts user-friendly domain names (e.g., www.example.com) into the numerical IP addresses (e.g., 192.168.1.1) used by computers to communicate over a network.

Example of domain name system 

When a user enters a website's domain name into a web browser, the DNS resolves that name to the corresponding IP address, allowing the browser to connect to the website's server.

Strategies of domain name system 

• Use reliable DNS providers: Choose reputable DNS service providers for reliable and secure domain name resolution.
• Implement caching: Employ caching strategies to speed up DNS resolution by storing previously resolved domain-to-IP mappings.
• Monitor DNS performance: Regularly monitor DNS performance to identify and address any issues promptly.
• Security measures: Implement security measures such as DNSSEC (Domain Name System Security Extensions) to protect against DNS-related attacks.
