- Networks
- What is the IP address of the computer you are using?
- What is the router you are connected to?
- What is the address of the DNS server you are using to resolve IP to domain names?
- Ping a friends computer. Only allow for a brief time, please!
- review: Data packet
- learn: Network speed
- activity: draw a diagram of your network at home
- learn: network hardware
- clarify: what is the difference between a switch and a router?
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".

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

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