Quarter+1

September 1, 2011
We will finish watching the movie about the history of the internet and summarize it together.



September 5, 2011
Those who need to take the What's in the Lab? quiz a second time will do this. When you are done the quiz, please watch the video ENGLISH Computer Science Unplugged - Part 1 Binary - 2005.flv on the T: drive (in the MSIT>Internet folder). When you have watched the movie, try to work out the following questions: 1. What number is 1101?

2. What number is 10111?

3. Try to determine what happens to the value of a binary number when you put a 0 on the right of that number. Example: Convert 1011 and 10110 to decimal numbers. How are they related? Try this with another number and see if your guess was correct.

4. Write 23 in binary.

5. Write 31 in binary.

6. ASCII is one example of how computers turn numbers into human readable characters. Research ASCII on the internet. What is ASCII? What is the number for the character "g"? What is this number in binary?

Bonus Link: Read this story if you are finished before everyone is done the quiz: @http://computationaltales.blogspot.com/2011/06/unhappy-magic-flowers-and-binary.html

If you are done this, you may practice your typing. For Quarter 1, you MUST type a minimum of 20 WPM, with 90% accuracy, for a 3 minute test on @http://www.typingtest.com (Miss Hines will pick the topic). Practice this - we will do our first test on the first day back from our time away!

September 12, 2011
Please complete the typing test when it is time. @http://www.typingtest.com

After the 3 minute test, please record your result here: @https://spreadsheets.google.com/spreadsheet/viewform?formkey=dHRZUExsU1hEeVdBczNVWDFyRjhCRGc6MQ

Then we will continue to look at Binary Numbers.

September 14, 2011
Grade 7's - make sure you pick up a binary numbers worksheet and you can start this at the start of class.

Grade 8's - please hand in your binary numbers worksheet at the beginning of class, if you did not finish it last time

Questions for you to answer (answer these in a Word document) 1. Review: What is a bit? What is a byte? 2. How many bytes are in a kilobyte? 3. How many kilobytes are in a megabyte? 4. How many megabytes are in a gigabyte? 5. How many gigabytes are in a terabyte? 6. And the ultimate question, how many bits are in a terabyte?

Now, try to answer these questions about IP addresses: 1. What is an IP address? 2. How do computers store IP addresses? (i.e. in what number system?) 3. If we use a system where the IP address look like 74.0.201.6, how many possible addresses are there? 4. Using the site: [] determine what your address is. 5. Can you find out what Google.com’s IP address is? (Note that this will take some poking around, and may change depending on your source!)

September 16, 2011
You will have approximately 10 minutes to answer the questions from above about IP addresses. Then, we will take up the answers. After this, we will watch a movie about networks - Warriors of the Net. This movie will also be available shortly on the T: drive.

September 20, 2011
We will talk about IP addresses and learn about some of the terms involved with IP. You are responsible to know what the following terms mean: -router -IP -gateway -packet -LAN Then, we'll act out packets going across a network. Finally we will try the commands ipconfig, ping, and tracert to learn a bit more about networking and how packets travel.

September 22, 2011
We will come back to IP once Pchum Ben is over, but for today, we will look at Cybersecurity and Cyberbullying. Find two people to join your group. As a group, you need to pick one of the following terms to research
 * spam
 * cybersquatting
 * worms
 * viruses
 * malware
 * spyware
 * index poisoning
 * hacking
 * phishing

and make a wiki page to answer the following questions: 1. What is your term about? 2. Why is it bad? 3. How does it show up on your computer? 4. What can users do to protect against it?

You will have a private wiki page until you are finished your page, at which point everyone on the wiki will be able to see it. Please make your page look pretty (add pictures or coloured text as necessary). As well, if you find any multimedia clips to add to your wiki page, feel free to add these.

When you are finished, take a look at: @http://www.brainpop.com/technology/computersandinternet/cyberbullying/ (we will watch the movie together, but you can read about cyberbullying here).

September 29, 2011
Start by finishing your wiki page with your group. Remember that your page is out of 5 - 1 mark for each question and 1 mark each for the presentation. We will have a chance to present these to the class when everyone is done.

When you are done, you need to answer these questions in a Word document: 1. What is cyberbullying? 2. Why do people cyberbully? 3. When is cyberbullying ok? 4. What are some things that you can do if you are being cyberbullied? 5. What is the best way to prove that you are being cyberbullied? When you have completed this, you may look through your notes from the internet work so far to prepare for a quiz on October 5.

We will watch the BrainPop movie together, along with another cyberbullying video.

October 3, 2011
If you are not done your cyberbullying questions, finish those now. When you have finished them, you may have some time to review for your quiz on Wednesday. Topics for the quiz: -History of the Internet -Binary and Data -Internet Protocol basics -Cyberbullying Make sure to review your notes. If you are missing some notes, please ask a friend to help you out. We may be able to get a good set of notes on the wiki! (History notes are already present.)

You also need to think about how you can present your information about Computer Security. You will be asked to do this after the quiz (possibly on Friday). Note that the computer security topics are not on the quiz.

October 7, 2011
No class due to the orchestra field trip.

October 11, 2011
Quiz! When you are finished, please take a look at: @http://www.20thingsilearned.com/en-US and read about Things 1, 4, 5, and 16. We will talk about these next class. Then we will have the computer security presentations. After this, we will look at meta-data!
