(12/11) Points are posted with final grades. They include all late work received through this morning and all the exams and quizzes taken at the exam times. Any errors or omissions you may find, please let me know.

It's a pleasure to see so many As and Bs and so many excellent LAN projects, even if looking at them can quickly blind me, it's good to see. Please, don't undervalue the importance of good-looking technical drawings in a portfolio and practice these skills whether you scored highly on the LAN project or not.

(11/10) Quiz #3 will be given at the last class meeting on Thursday the 19th. The exam time for the class will be used for re-taking one of the earlier quizzes or for a 1:45 exam for 60 points that has questions from all three quizzes and will replace the earlier scores. Exam times can't be changed, but students can attend either that's convenient. Exam times are:

The LAN Project's due date is unchanged, Thursday the 12th. An email will be sent from BlackBoard for you to reply with a single pdf with your project attached.

'The Cloud' is just a bunch of servers running in Data Centers and IX-Internet Exchanges. This topic describes the data centers they run in. Any network that needs to be up and running to do business should be in a data center or a network closet that has data center features...

(10/27) Class today was a read thru and Q&A of the Memo from the Boss, calling out stuff that needs to be on the Simple Bill of Details due the 29th. There's another chance for Q&A in class on Thursday.

(10/22) Class meeting 10/20 Walkthru Memo, Floorplan, and Rack Diagram

(10/20) The LAN Project is due November 12th. Please read through the Memo From the Boss with a highlighter and come up with the list of hardware, software, and services to get the new warehouse on-line. Study the floorplan and rack diagrams and figure out where everything goes.

A Simple Bill of Details' is due October 29th showing what you plan to purchase for the new DMLH Warehouse. Be specific with models and specifications. The final project needs separate purchase orders for each supplier, but this simple bill of details can be in a single spreadsheet or handwritten notes.
