Personal Reflection of Technology on Current and Future Applications Our assignment this week will look more like a personal, journal reflection. It will incorporate your own connections, and applications to key terms, concepts, and ideas presented throughout the past 7 weeks (including material from our week 7 readings, lectures and videos). After choosing one topic…

Iteration Introduction In Iteration 3, you created a DBMS physical ERD that contains primary and foreign keys, which gives you the structure of your database, but does not provide a place to store data. Databases with no data are not useful, so, in this iteration, we add attributes to our DBMS physical ERD. Attributes allow…

CMIT 351 Project 2 Description Intro: ACME University IT has reviewed the results from your prototype and now wants to move forward with an adjusted set of requirements. You will need to implement layer 2 segmentation to control broadcast domains and increase Local Area Network (LAN) performance but also provide routing between segments. Scenario: IT…

Part 1: Design the Local Area Network [paste your network diagram here]   Part 2: Create the basic switch configurations 2.1 Cable the network Describe in a few sentences which devices connect to which other devices using what specific kind of cable, on which specific interfaces? For example: 1. I connect an Ethernet cable on…
