There are about 4 months and 9 days until school ends. How are you going to use that time to make sure you do your best?

 

Daily Note

Let's review networking - test on Thursday. 

 

  • Identify different types of networks.
  • Outline the importance of standards in the construction of networks.
  • Describe how communication over networks is broken down into different layers.
  • Define the terms: protocol, data packet.
  • Explain why protocols are necessary.
  • Explain why the speed of data transmission across a network can vary.
  • Outline the advantages and disadvantages of wireless networks.
  • Describe the hardware and software components of a wireless network.
  • Describe the characteristics of wireless networks.
  • Explain how data is transmitted by packet switching.
  • Outline the characteristics of different transmission media.

 

  • Identify the technologies required to provide a VPN.
  • Evaluate the use of a VPN.
  • Explain why compression of data is often necessary when transmitting across a network.
  • Describe the different methods of network security.
  • Evaluate the advantages and disadvantages of each method of network security.

 

A little less comfortable

Process

You should be revising our content for 20 minutes each day. As you learning about networking topics you should be asking yourself how you can apply your understanding (how do I go from theoretical to practical). I would love to hear from you, "How can we use this information practically?". 

Product

As you are learning you should be taking notes, and developing a cookbook or spellbook. Most system administrators have a book of hints and tips they keep with them. You should have a digital text file or written notebook with helpful reminders to understand the deeper parts of your system. 

Content

At the end of the day, you should be able to apply your understanding of network issues to solve problems. You should understand the maxim "Packets never lie". 

A little more comfortable

Process

You should be revising our content for 20 minutes each day. As you learning about networking topics you should be asking yourself how you can apply your understanding (how do I go from theoretical to practical). I would love to hear from you, "How can we use this information practically?". You should be developing study guide for yourself, and using the tools we learn in class to see what is really going on with your computer, from a networking point of view. It would be good to run some simple experiments; as you are monitoring network connections, see what different applications do with your network. Any processes using network without your knowledge?

As you are learning you should be taking notes, and developing a cookbook or spellbook. Most system administrators have a book of hints and tips they keep with them. You should have a digital text file or written notebook with helpful reminders to understand the deeper parts of your system. You should have backups of this helpful little guide of tips and tricks. Feel free to collaboratively share this with friends. 

Content

At the end of the day, you should be able to apply your understanding of network issues to solve problems. You should understand the maxim "packets never lie". At a more comfortable level you should be applying your understanding of networks to see how applications are using networking resources. Whenever there is a network configuration issue or problem, you should know "about" where to look. 

Statement of Inquiry

The big idea for today is Networking.

The essential questions for this topic are:

How does a computer network really work?

It takes time to explore and really understand a big idea. If you want to
learn more about networking (which is connected to today's daily note), please click here .

We are learning this because as a designers must understand scientific and technical innovation. Designers use systems, models, methods, and processes to solve problems.
