Objective
By the end of this lesson, the student will be able to understand the basic concepts of computer networking, specifically how domain names are translated into IP addresses, and the role of DNS in this process.
Materials and Prep
- Paper and pencils for note-taking and drawing.
- A whiteboard or large piece of paper for visual aids.
- Access to a computer or device with internet for demonstration (if possible).
- Basic understanding of what a website is and how it works.
Activities
-
Domain Name vs. IP Address Game: Create flashcards with different domain names on one side and their corresponding IP addresses on the other. The student will match them correctly to reinforce the concept of how domain names work.
-
Draw the Internet: Have the student draw a simple diagram of how the internet works, including elements like computers, servers, and the DNS. This visual representation will help them grasp the concept better.
-
DNS Relay Race: Set up a relay race where the student has to 'find' the IP address of a given domain name using clues you provide. This can be done in a fun, interactive way to engage them in learning.
Talking Points
- "Every website you visit has an address, just like your home. This address is called a domain name!"
- "But computers don’t understand domain names; they understand numbers called IP addresses. It’s like how you might not know your friend's phone number but know their name!"
- "The DNS, or Domain Name System, is like a phone book for the internet. It helps your computer find the right IP address when you type in a website."
- "When you type a website into your browser, your computer asks the DNS for the IP address, just like asking a friend for someone's phone number!"
- "Understanding how this works helps us appreciate the technology behind the internet and how we connect with information all over the world!"
