The download include 3 PowerPoint Presentations which are designed as an introduction to Computer Networking in the new GCSE Computer Science.
The lessons were designed to give my Key Stage 3 students an insight into the topics that will be covered at GCSE Computer Science in advance of choosing their options. If using them for GCSE I hope they can easily be adapted and extended.
Lessons 1 includes an opportunity for students to build a prototype network. I used wool to represent cables (different colours for Ethernet and Fibre) it worked quite well. If you have resources for student to build a computer network then all the better.
Lesson 2 enforces the top level concepts covered in Lesson 1 by starting to include some detail about the other components required. The students can then simulate a network on line with a link included in the last slide.
Lesson 3 concludes the scheme of work giving students an insight into how data is transferred in packets - The animations in the presentation really helped. In this last lesson there is a link to you tube video on How the Internet Works (8 min). There are some more video link, at the end of lesson 3 (that could be used at the end of any of the lessons) as an extension. Inside a Google Data Center (6 min) and How Big is Google? (12 min). The last lesson concludes with a slide showing what happens in 60 seconds on the internet.
I've omitted the more involved technical objectives of the specification. The presentation I've included many animations that will satisfy some differentiation.
The Scheme Of Work includes:
- Introduction to Networks Lesson 1 - LAN and WAN
- Introduction to Networks Lesson 2 - Network Components and Ethernet
- Introduction to Networks Lesson 3 - Routing and the Internet
Objectives are:
- Understand where networks are used and types of small and large networks
- Name key components used on a network
- Explain the difference between a hub and a switch
- Explain the purpose of servers on the network
- Understand ethernet copper and fibre-optic (the slides that shows the standards are intended as a overview of technical terms)
- Describe how packets of data a transferred between computers (and through devices)
- Understand how packets are sent via different routes
- Appreciate the size of the internet
