Introduction

Welcome to class, Year 7 students! Today we're diving into a crucial aspect of computer science - computer networks. But before we start discussing it in detail, let's go on a little adventure!

Treasure Hunt

I've hidden five cards containing clues around the classroom. Each card has a question related to computer networks and leads you to the next clue. Work in teams of two or three and race against the clock to see who can find all the cards first!

The Questions

Here are the questions that you'll need to answer in order to find all the treasure hunt clues:

1. What is the definition of a computer network?
2. What are some of the benefits of using a computer network?
3. Name three types of computer networks.
4. What is the difference between LAN and WAN?
5. Name two examples of network topologies.

Conclusion

Once you've completed the treasure hunt, we'll go through the answers together as a class. I hope you'll have learned a lot about computer networks and had some fun along the way!
