Lesson 3 P2P & Client-Server

Student Paired/Group Work Working in groups as instructed by your teacher you need to prepare a 6 minute presentation about P2P and Client-Server networks. Key Questions to cover: Explain the term client-server Explain how a client-server network functions What is the function of the client within a network Explain the term P2P Give two types of devices/resources which can be shared on a P2P network Give 3 advantages and 3 disadvantages of using peer-to-peer networks. P2P networks and connections are usually throttled by internet providers, find out: What does the term “throttled connection” mean? Why do they throttle P2P traffic? Why do they have a bad reputation? Presentation Ideas Paper based - multiple large sheets of paper Powtoon Prezi Pear Deck Video Screen recording using something like paint PowerPoint Google Slides This a research task for students, they can work in groups of 2 or 3 at teacher discretion. Give students a choice on how to present this.

Lesson 4 The Internet & WAN’s Understand the difference between the internet & the WWW Acknowledge that the internet a worldwide collection of connected networks Understand the uses of IP & MAC Addressing Describe what is meant by: DNS

Student Task Explain the purpose of an IP address Explain the purpose of an MAC address When data is sent from one computer to another across the internet, the data is split into packets. Give 4 items that will be included in each packet in addition to the data itself. Where would these 4 items be stored within the packet?

Lesson 5 VPN, Hosting & Cloud the internet as a worldwide collection of computer networks: DNS (Domain Name Server) hosting the cloud the concept of virtual networks.

Student Task: Hosting Paid and unpaid web hosting services - research online the benefits of paying for web hosting over getting it for free. Things to consider: Which companies offer hosting - find examples How much do they charge? What do you get? Do they all offer similar services for a similar price What's the downside of choosing a free option? Can you host your own website? If yes what is required?

Student Task: CLoud Storage Tadcastle Grammar School has an ageing teaching staff who have a limited understanding of technology, teachers create all of their lesson resources on computers and save these files onto USB memory sticks. However these memory sticks are regularly lost meaning the work has to be redone as it is not backed up, the school's new Head of ICT Mr Bingle has convinced the technicians to invest in cloud storage for all staff. Create a poster that will convince and explain to staff why they should either stop using USB memory sticks or at least back them up online. You will need to include a little info explaining what cloud storage is. Use a blank slide in this document Google Drawing which can be accessed here
