Learn: DNS Servers

Welcome!Today we'll learn about DNS Servers. These are essential for how computers find websites on the internet. Let's explore how they work step by step.

What is a DNS Server?A DNS Server (Domain Name System Server) translates domain names like 'www.example.com' into IP addresses that computers use to locate websites. This is important because people find it easier to remember domain names than long strings of numbers.

How does DNS work?When you type a web address into a browser, the DNS server looks up the corresponding IP address. It acts like a phone book, connecting human-readable names to machine-readable addresses.This process ensures websites are accessible even if their IP addresses change.

Why is DNS important?Without DNS servers, users would need to remember IP addresses like '192.168.1.1' for every website they visit. DNS makes the internet easier to navigate and ensures websites remain accessible even if their IP addresses change.

DNS Lookup ProcessWhen you visit a website, your computer sends a request to a DNS server. If the DNS server knows the IP address, it responds immediately. If not, it queries other DNS servers until the IP address is found.

Review Time!Great work! You've learned about DNS servers and how they help computers find websites. Now let's test your understanding with a few questions.

Final ThoughtsWell done! You now understand how DNS servers work and why they're essential for navigating the internet. Keep up the great work!
