DNS (Domain Name System) is like the internet's phonebook. It translates human-readable domain names (like www.example.com) into IP addresses (like 192.168.1.1) that computers use to communicate with each other. Understanding how DNS works is crucial for anyone who wants to navigate the internet efficiently.

Key Points About DNS

  • Translation Process: When you type a domain name into your browser, DNS translates it into an IP address.
  • Speed: DNS caching helps in loading web pages faster by storing IP addresses of recently visited websites.
  • Redundancy: DNS has multiple servers to ensure that if one server fails, others can take over.

Why DNS is Important

  • Ease of Use: Without DNS, you would need to remember IP addresses for every website you want to visit.
  • Scalability: DNS allows the internet to scale without requiring users to memorize IP addresses for each new website.
  • Security: DNS plays a role in preventing certain types of cyber attacks.
