Daily Note

Let's review networking

 

  • 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.

Statement of Inquiry

The big idea for today is Computational thinking.

The essential questions for this topic are:

How do we think about problems in a way which makes them solvable for a computer?

It takes time to explore and really understand a big idea. If you want to
learn more about computational thinking (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.
