Final Day 2019 – So Long, Farewell, Auf Wiedersehen, Goodbye

Objectives:

  • Bid a fond farewell for now.
  • Tell Mister M how he did, and help him improve future classes.
  • Look forward to the future.

Student-Friendly Objectives:

  • I can say “Happy Trails” until we meet again.
  • I can remember what Mister M taught me, and use it to troubleshoot, fix, secure and protect computer systems and networks.

Links:
Google Classroom

Topics Discussed:

  • Networking and Operating Systems
  • Class Survey
  • Summer Vacation

Assignment:

Hello, and congratulations! You successfully made it to the end of Networking and Operating Systems 1-2H! I hope this was a fun and productive class for you, and that you learned a few things that will help you in your future endeavors.

If you could take a moment to let me know how I did, and how I can improve for future classes, I have attached a brief questionnaire on the Google Classroom page. It’s not for a grade, but your feedback will help me out a lot, and I’d appreciate it if you took a moment to fill it out with your honest opinions.

Now that we’re done, above all else:

  1. Use your powers for good, not evil. Remember the lessons of Spider-Man: “With great power, comes great responsibility.” You now have skills and abilities far beyond those of your average computer user. Use them to protect and defend, never attack.
  2. Keep using your skills! Take more computer classes and keep learning as much as you can about PC, Mac, Linux, Security and Networking technology. The more you use your knowledge, the less likely it will slip from your memory. The more you know, the more effective and valuable you are, and as more devices connect to the global network, Technical Support and Cyber Security especially will remain rapidly growing and highly lucrative fields for decades to come.
  3. Do what you love, and you’ll never work a day in your life. If you love working with computers and technology, then pursue it. If computers are just your hobby, don’t make it a job – it’ll just suck the joy out of your hobby. If you truly love working with computer hardware and software and networking technology, and you love solving problems with technology, then by all means pursue a career in the Computer Science field. As long as you love what you’re doing, every day you’ll look forward to going to work and the financial rewards will follow.

It has been my great pleasure to accompany you on your journey into Networking and Operating Systems this year. I hope that you enjoyed this class, and continue to use your newfound powers to solve the problems that are related to and created by technology, and to protect your own and others’ computer systems from the constantly emerging and evolving range of threats – both online and offline.

Out Today – September 17th, 2018

Good morning! Sorry I couldn’t be there with you today, but I’m taking care of some personal business off campus.

Continue working on the Chapter 2 LearnSmart module today. Don’t forget that it is due on Wednesday, Sept. 19th, so you have time to work but no time to waste.

Certification track students should continue studying for your A+ Certification Exams – I will be doing a progress check soon, so make sure you have some progress to show me.

Everyone has work to do. Do not make the mistake of using my absence as an excuse to use this day to chill, watch movies, play UNO or research Yugi-Oh card prices (You know who I’m talking to…).

Be nice to the substitute teacher, thanks for all your hard work, and I’ll see you tomorrow!

Wireless Networking – DIY Directional Antennas Project: Revision Phase and Final Testing

Objective:

I can demonstrate my understanding of computer networks, network operating systems and wireless networking by assembling a directional antenna with the intent of establishing and sustaining a 2.4 GHz wireless signal at a distance of greater than 100 yards.

Topics Discussed:

802.11 Wi-Fi spec
Directional Antennas
Waveguide Antenna
Yagi Antenna
Flickenger design Antenna

Assignment:

Today, we will begin the final revision phase of our directional antenna project. Last week, two teams tied with equivalent dB gain readings on our test receiver router, but only one can win! Remember that the goal is to sustain a 2.4 GHz Wi-Fi signal over a minimum distance of 100 yards (300 ft or ~92m) and the winner will be the one who sustains the highest (negative) dB reading and signal quality over the longest distance.

We will conduct final tests the week of February 21st (Monday the 20th is a holiday!). To be considered a success (and receive credit for the project), your antenna design must be able to sustain at least a one-bar wireless signal over a 100 yard distance (the length of the football field). If your team is not present for the final test or you do not have a working antenna to test on Tuesday, February 21st, you will receive a zero on the second half of this project without the opportunity for make-up. (We’re only going out to the field once.)

Reminder: The team (or individual) that produces the antenna that can reliably sustain the highest gain signal over the longest distance will receive a personal pizza and wings party, to be held while everyone else writes a four paragraph personal reflection describing their participation in this project.

Good luck, and remember: Your antenna doesn’t have to be perfect, it just has to be better than everyone else’s.
