WEEK 7 SESSION: CO-OP AND BASIC NETWORKING CONCEPTS

The Cooperative Group

Excerpt from IT Infrastructure and Management lecturer on Tuesday:

Dear Mr Sutherland,

We appreciate your concerns about your ability to govern the Co-op group. We believe there are possible uses of technology to add value to your organisation’s future operations, in order to turn things around:

Dawn of a new Era

  • Personal video conferencing = more meetings, greater productivity and better results across the organisation.
  • Large scale physical rooms replaced by smaller virtual footprint
  • Face to face video conferencing more transparent
  • Social interaction is taken away with video conferencing?

The rise of Video conferencing innovation will power corporate growth

  • Video conferencing saves money on travel, time costs
  • Natural-disaster-proof and health-epidemic-proof communications
  • Business transactions can be supplemented by video

VC goes viral

  • Human resource management can be complemented
  • Mobile meetings ad-hoc and post-hoc
  • If you are quick to adopt you can be 2-5 years ahead of competition (ref)
  • VC is as destructive as a phone call but more productive

The new rules for VCA

  • New etiquette and protocols, e.g. turn taking machine, dress code
  • Back light
  • Eye contact
  • Special case job interview

Genius of collaboration

  • The best minds have used the technology
  • Telepresence for core business of banking
  • BYOX, cross platform video, etc.

Truly Unified

  • Share rich media and facilitate ENG (Electronic News Gathering)
  • Browser/mobile app as a client for the server technology – therefore inclusive to everyone
  • Connection performance is important
  • Need to balance cost of system versus savings in utilisation

Tuesday’s lecture with Paul was about The Cooperative Bank. we talked about how Euan Sutherland the Chief Executive of the Co-op Group resigned from his post on Tuesday 11th March 2014 because he deemed the company “Ungovernable”. Our task was to come up with new business ideas that could benefit the Co-op Group to become a stronger company. To do this we used various case studies that will come up in the exam and they are all listed above.

Basic Networking Concepts

In the tutorial, we were discussing (in lengthy detail) about Networking, we talked about Networking Fundamentals, Major types of networks, Networking media, Types of servers, Topologies and Planning in network design.

**I tried to upload the slides, but i couldn’t so I uploaded the images instead**

Here’s a few diagrams that cover these things:

WEEK 6 SESSION: VIDEO CONFERENCING & DATA PROCESSING

In this week’s Lecture & Tutorial we talked about Data Processing and Video Conferencing. In the lecture, we covered things like Analog and Digital Data Communications. Data are Entities that convey meaning or Information, Signal is electric or electromagnetic representation of data, Transmission is the communication of data across a computer network by the propagation and processing of signals and signalling is the physical propagation of the signal along a communication medium. The analog data is continuous on interval voice and video and data collected by sensors, such as temperature and pressure. Digital Data are discrete values, text, integers, binary data.

In the Tutorial, we did a dry run of what would happen during a typical Video Conference. The aim was to develop administrative and technical skills for unified communications. Everyone in the class was assigned various roles:

  • Presenters
  • Technical manager
  • Public testers
    • iPad
    • Android
    • laptop
    • mobile
  • LSBU
    • campus desktop
    • Wi-fi tablet
    • Wi-fi mobile 
    • Webcam support
  • Sound engineer
  • Mobile/txt support monitor

To hold this video conference, we used Adobe Connect (some used the computers, some people used there tablets). I chose to be a presenter along with 2 others and my task was to make a short presentation and present it on the dry run conference. Along the way we did run into a few problems, sound wasn’t coming out from every speaker, the webcam was lagged on the mobile devices, white noise on the screen (one of the presenters vanished) and not everybody was able to log in, but overall it was a success.

WEEK 5 SESSION: OPNET IT GURU

In my IT Infrastructure tutorial session today, we were looking at small networks and how they work. To do that, we used a software called OPNET. The OPNET IT Guru software was created for introductory level networking courses, and designed and tested to be used with popular classroom lab manuals.

We started using IT Guru by working on one of the tutorials for the entire session. We were learning how to create a network, collect statistics about network performances and analyzing those statistics and that involved creating the network itself and doing a live test.

By the end of the session something like the example below would have been produced:

OPNET pic

(OPNET version)

OPNET expansion network

(my finished version)

After running the mock network, I collected my results to answer the main topics for the tutorial session:

  • Will the server be able to handle the additional load of the second network?
  • Will the total delay across the network be acceptable once the second network is installed?

 

Here is my results for my network:

OPNET results 2

 

OPNET results 3

OPNET results 4

OPNET results 5

Till next time……………………..

 

 

WEEK 4 SESSION: SURPRISE TEST!??!?!?!

Image

I’m sorry if this is not seen as “Correct Blogging” but whatever, to put it short an sweet just like the title says i had a surprise test. When i say it was a surprise, it was surprise not a single soul in the room was in a good mood when Patrice said that. The test originally meant to take an hour (but in reality for me it took 25mins) and it was covering all aspects of Computer Systems (Hardware and Software) even though it was a surprise test, we wasn’t getting marked (thank GOD!!!!!) it was just to see what we knew and how we can improve our knowledge. After we finished the test , we swapped with other students so it can be marked. out of 45 questions the pass mark was 24 and my personal mark was 20 and that goes to show that i have a lot of work to do academically.

 

That’s all i can remember really because i forgot to blog about this last week.

Week 3 Session: Blogging & Video Conferencing

BLOGGING

 

In the lecture i had on Tuesday, the things we covered was Blogging and Video Conferencing. What i’m going to talk about first is Blogging. Our lecturer Paul Carden talked the type of things that are usually considered actual “Blogging” and also described them as “Blogging Levels” from Level 1-8 with 1 being the lowest and 8 being the highest:

Paul mentioned that just posting assignments on your blog site is not considered “blogging”, posting assignments is just like posting something on a noticeboard showing information not pure understanding. “Journaling” is not blogging just documenting your Life Story in short, simple updates. Posting links to websites is not called blogging it’s called “Laziness”. A typical blog is reflecting writing that articulates a deep understanding of something that caters for the audience and over a long period of time it builds on older posts, links and commenting that my curious reader, is TRUE blogging.

Here is an example of a “far from perfect so-called blog”: NOT BLOGGING .

** This is a little off topic but i personally found this funny and good advice of how NOT to treat your BLOG .**

*** Another side note, i don’t want to get sued for using links so i’m just going to shout out to all the owners of the sites i pasted if they happen upon this post (which i doubt but still i’m just covering my ass). ***

And here is a much better example of a well structured blog: REAL BLOGGING .

 

 

 

VIDEO CONFERENCING

 

Another thing that dear Paul discussed was Video Conferencing, this mainly involves using a Webcam that was used during the MSN days LOL:

Nowadays having sessions can be done using a mobile device:

Not only can Video Conferencing be done on a one-to-one basis, it can also be done on a wider scale like for presentations, group projects, international business meetings or just to chat to a friend. Below, i’m including a few extracts from the lecture that was discussed:

(End of Extract)

————————————————————————————————————————-

Another thing we did was use Adobe Connect. Adobe Connect is a web conferencing platform for web meetings, e Learning, and webinars. It powers mission critical web conferencing solutions end-to-end, on virtually any device, and enables organizations from leading corporations to the U.S. Department of Defense to fundamentally improve productivity. How the process works is the session has Hosts & Presenters who are responsible for organizing and maintain the session and then there’s the Participants who’s soul purpose is simply get involved in the session and contribute in any way they can.

(Source: http://media.dexigner.com/article/22594/Adobe_Connect_9_Webinars.jpg )

What’s good about this application is that you can also use your mobile device to connect to the conference by using the camera on their phone. Another addition is that you can use Social Media to get involved as well (Twitter, Facebook etc.).

 

**** One more side note i like to add that i am enjoying my lessons very much and i’m enjoying using WordPress to blog about it as well. I have this feeling that i am going to burst into tears when it comes to the actual coursework so i am just bracing myself for that day. ****

Week 2 Session: Networking Fundamentals

In my Week 2 session, i was asked to look at the sorts of information that businesses store, manage and transport across the network – audio, image, video and data.

First off i was required to do a Speed test (see below):

speedtest

  • Ping = 22ms
  • Download Speed = 96.39mbps
  • Upload Speed = 22.97mbps

Then we downloaded a “Large Image” from Google and we monitored the time it took for each image to download:

ESC_large_ISS022_ISS022-E-11387-edit_01

(source: http://upload.wikimedia.org/wikipedia/commons/c/cc/ESC_large_ISS022_ISS022-E-11387-edit_01.JPG)

  • jpg format download time = 1.7 seconds (file size = 1.02MB)
  • bmp format download time = 1.4 seconds (file size = 34.8MB)
  • gif  format download time = 1.5 seconds (file size = 6.38MB)
  • png format download time = 1.8 seconds (file size = 11.8MB)

We also used another piece of software called  Irfanview to save the image into different formats (jpg, bmp, gif, png) and they came up with each various file size shown above.

After a small lecture, we had the opportunity to re-create a typical network in a chosen computer lab using Microsoft Visio 2010 (see below):

topology

As this is my first attempt, obviously it’s not going to be the best looking one but i’m able to break it down easily. i tried to keep to the floor plan as best i could so on the left there is 3 rows of 6 PC’s and on the right there is 4 rows of 3 PC’s linked up via Ethernet cables and they are all linked to a network switch which is then linked to the router which is linked to the server which is linked to the cloud (strategic guess).

And that is what i’ve covered and gained from this lesson today.

till next time………..

Life is good…..

I was wondering what to call this so called blog post so I decided to quote one of Nas’s albums (“Life is Good”)

Even though it’s pretty much been the beginning of the year things have been going good, I’m starting my driving lessons, I’ve been baptised (I’m a Jehovahs Witness btw those guys who “annoy” you every Saturday morning?????) and I’m navigating 3 jobs and uni at the same time. Every yeah I always run into a new set of problems but for once I can actually say that I’ve started my year off with a bang.

Just a random thought I just came up with lol
