IT Infrastructure & Security - Fall & Winter 2018


(8/27) Get Visio! Visio is the de facto standard 2D CAD tool for all kinds of modeling in IS. We use it for network diagrams and floorplans, INFO361 uses it for UML diagrams, INFO364 for database. It's the Swiss Army Knife of diagramming tools. Please use it or have a good reason to use something else. It is a Windows app so Mac users need to get virtualized... I've seen a couple not-as-good-as-Visio drawings with google's office tools, but as yet haven't seen any make a rack diagram that is almost photo-realistic using VisioCafe templated items.

(8/27) Mac Users & Windows Users Hankering to Virtualize: The IS Department's Net Techs support IS Majors' MSDNAA Software and Virtualization issues, especially Mac host with Windoze guest. They're expert with Oracle's Virtual Box, Apple's Parallels & Boot Camp, HDD & USB, and what combination is optimum for your Mac or PC, or if you've got the space to do it... They've seen it all and are patient, caring types who will help y'all noobs onboard new things.

Most students with Macs who attend one of the Virtualization & MSDNAA Installation Seminars leave with their machine virtualized or dual-booted and able to run Windows & MSDNAA software. The net techs have also been helpful with running Kali Linux

F I N A L Grades from the Spring semester are posted. This Fall's will be similarly assigned, hopefully more Aces.

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. Characters are represented as ASCII, EBCDIC, and UniCode. When data moves from one system to another, there's usually some translation or conversion involved... (Study Questions)
