Unit 11 - Networking Lesson 4

Lesson 4 - work that needs to be done!

In lesson 3 we learned about how files are broken down into packets when it is sent over a network.

There are 2 ways of sending the packets - circuit switching and packet switching.

In order for computers to be able to send and receive information (data) on a network, they need to have an IP address.

1.  Find out what IP stands for, what an IP address is and why it is needed.  The link below may be useful (however, other websites are available!).

http://www.myipnumber.com/my-ip-address.asp

2.  On a new Blog post for this lesson, write down what you have found out about IP addresses and why they are needed for computers on a network or using the internet.

3.  Find out the equipment that is needed to set up a basic network of 5 computers that can connect to the internet.  List the equipment and how it is used (what it's needed for) on your Blog post.

4.  Linked in with IP addresses and networks, can you go back to the presentation for Lesson 1 in this unit when you had to explain why setting computers up as a network was a good idea for businesses.  Make sure that you have finished this presentation and that you have included diagrams for each type of network design (topology) - bus, ring and star.  Make sure you have written down the advantages and disadvantages of each design and why one you'd recommend to use.

5.  Make sure you have shared and linked this presentation correctly and that the Blog post it is pasted on to has been published.

Make sure all work for this lesson and previous ones is finished and published.  Any unfinished work is to be finished for homework

1.  Have a go at the quiz.  You need to score at least 4/6!

2.  Open up a new Blog post and title it the same as this post.

3.  Write a description of how information is sent around a network as packets. Try and link your explanation with work we've done before on binary, etc - get those level 6 grades!!

4.  Explain the differences between circuit switching and packet switching.

5.  If you wanted to hack into a network to steal information, which type of switching (circuit or packet) would be the hardest for you to steal useful information?  Explain why.

6.  When you have finished this, click Publish!

If you don't finish this in the lesson, please finish it for homework

Unit 11 Networking, lesson 2

Lesson 2 - today's tasks!

1.  Go to Learning Computing, Unit 11 Networking, lesson 2.

2.  Open the teacher's presentation and read through each slide.  Go through the slides in overview format, don't click the 'Present' button as you need to read the notes on slides 8 and 9 for extra info (normally I'd tell you this info as I went through the presentation in class).

3.  Ignore the 2 video links on the lesson as these are no longer available on YouTube.
