Welcome all Hardware, Software, and Networking  TEC722 class members.  We are learning about the Windows Command Line Interface.  For today's class we will do the following:

1. Checkin to class by sending me an email (helpdesk@cgcseagles.org) on or after 11:41 AM today to let me know how you are doing and if you need anything.  This is very important, as attendance is being taken.

2. PART ONE: Build a Virtual Mansion (Directory Navigation)

Today we will first build a Virtual Mansion using Directory Navigation.   Learning to navigate directories can be tedious, so we will turn it into a construction project.

3. Go to this comand line online demonstrator: https://learnmandu.com/

4. The commands you will practice: mkdir (or md), cd, cd .. (cd followed by a space and 2 dots), dir

5. The Activity: You are an architect building a virtual mansion on your Desktop. First, you will create a main folder called Mansion.  Then navigate to your Mansion using cd.  Once you are inside your Mansion, you will create four rooms: Kitchen, Library, Basement, and Attic.  To prove you know how to move around, navigate back to the Library and create a sub-folder called Secret_Passageway.

6. Navigate back up to the Mansion folder, and typing dir .  

7. PART TWO: The Internet Road Trip (Basic Networking)

This second exercise connects the abstract command line to the physical reality of the global internet.

8. Commands you will use: ping, tracert (Trace Route)

9. The Activity: You first will ping your favorite website (e.g., ping google.com or ping nintendo.com) to see how many milliseconds it takes for data to travel there and back.  Second, you will use tracert.  You will trace the route your Internet connection travels to reach a foreign website (like tracert tokyo.jp).  Be sure to watch as your computer "hops" from your local router, to your ISP, across underwater oceanic cables, and finally to the destination server.

10. Virtual Check-in: Show me your newly constructed Mansion and the places you have traveled across the Internet.  Click the Download symbol at the top right (as shown below), and save the TXT file to your device.  Then send me an email with that TXT file showing your work.

11. If you need help with the commands, click the Commands button at the top right.  Also, I want to emphasize that the command line is unforgiving with spelling and spaces. If you get an error, remind yourself to check your command syntax before getting frustrated.
