Introduction to the World Wide Web and the Internet Networks Introduction to the World Wide Web and the Internet

Objective We’re learning to understand the difference between the Internet and the World Wide Web Know how information is distributed across data packets. Know how I.P addresses are used to identify our location on the internet.

Your teacher will lead you in an activity at this point. What is the internet? Your teacher will lead you in an activity at this point.

The internet is a group of inter connected networks. What is the internet? The internet is a group of inter connected networks.

Devices connect us Use the activity sheet and list as many devices as you can that allow us to connect to each other. This shouldn’t take longer than 5 minutes: Explain to pupils that each of these devices allow us to connect to each other. All of the devices use a number of different methods to connect us to each other. When all of these devices get together, they create a network of computers. Your mobile phone is connected to your Xbox, your xbox is connected to your sisters phone and so on.

So what is the world wide web? Spend a minute and think about what the world wide web could be… (Teacher lead activity) WWW…………

The World Wide Web We now know that we need a number of devices connected together. This makes the internet. The world wide web is a collection of web pages found on this network of computers. Your web browser uses the internet to access the web. This video will help explain this. Watch the video with students, they will be able to watch back at it later and they can use it to help them fill out the work sheet.

IP Address Each of our machines have an I.P address: Go to: - https://www.whatismyip.com This is your location on the internet. No matter what you do, you’re traceable.

The problem is, it’s difficult to memorise every single I.P addres. IP Address The problem is, it’s difficult to memorise every single I.P addres. This is why we have a DNS. A Domain Name Server. This is like a database of our I.P addresses and our domain names. See the example:

Data Packets Information is too big to be sent as a big chunk of information. It has to be split into something called data packets. Each data packet has pieces of information built into them. This is shown on the next slide. You’re going to send your own data packets around the class.

Data Packets Your teacher has given you a piece of paper. Each packet has the following information: Sender (I.P Address) Recieve (I.P Address) Total Packets Packet number Get each student to draw a picture and split it up into 4 pieces. They should write down who they want to send it to. Who it is from, how many packets and the packet number I.E 1 of 4, 2 of 4. They should then send the packets around the classroom to get to another student.

Activity Use the computing website and download the worksheet. Answer the questions and print this for your teacher Start producing a blog post, video or poster depending on what your teacher requested. Make sure that you include information from your worksheet and make sure that you show all of your objectives have been met.
