IT Infrastructure & Security - Spring 2019


(2/19) Virtualize your machine! I'll post a 5 point bonus for anybody who brings their notebook computer virtualized and running two OS, or a dual-booted older PC or Mac that's not good for virtualization. Windows users, nobody has any reason to run a virtual Mac, and I suggest Kali Linux as the guest OS...

George Akpakli's our network technician and will consult one-on-one. He provides info about MSDNAA and his contact in this pdf: ISY Briefing Spring 2019.

Silma Hassain can also help with most virtualization and MSDNAA issues at her tutoring sessions.

(2/19) The LAN project is afoot. Please read the pages for the project and be ready to get questions answered in these next classes before Spring Break. Recently, an alarming number of these projects have been rejected on first submit because of sloppy work or inattention to the specs and I'd rather see 100% of the acceptable and Ace material. This is a challenging project for many noobs and helps develop valuable skills for work in IS and IT.

The link on this page was edited Feb 19th in the morning so if you've seen it before please check the updates for this semester. There are several versions of the project that might pop up if googling, so make sure you're using this semester's specs from the link below.

Put the doc package including summaries, diagrams, and bill of details in your portfolio along with other stuff that shows your interest and enthusiasm for the 'brand skills' of the career poath you'd like to follow. We recommend students keep a brief portfolio at LinkedIn and put full projects, code, and other exhibits from courses at GitHub so hiring managers can get an eyefull of your best work as they decide. When you go up against somebody else for a job, if they have a portfolio and you don't, they'll get the job.

(2/13) VCU IS participates in a Temple University study of IS graduates' jobs. It's one of the measures used to assess our program for continued ABET accreditation. It's a pleasure to pass along good news that y'all appear to be heading out into a favorable market! Here's a pdf with the results of their 2017 study: IS Job Index

(1/15) Final Grades & Points are posted from last semester, this semester's points will be similar. It's a pleasure seeing A and B are the most earned grades! We've got a lot of good students working through our IS program!

Data Representation

Computers are Binary machines but they keep and compute all kinds of data. Numbers are represented more or less directly as Binary, Decimal, and Hex Integers, Float, and Decimal.
