Blogs I like from fellow classmates

Everyone in our IT class has started a blog as part of the course. Some are happier than others about this.

Heres a selection of the ones which I find amusing.

Check them out 🙂

Information Processing Cycle

aussiegeekgirl 2 Comments

Hello, now the newest thing we have learnt about in IT is the information processing cycle which is the process information goes through before we see it. Also we have been learning about spreadsheets, so I am sure there is a spread sheet task coming your way soon.

I have made another table describing the steps, what they do and an example. I know this is very exciting stuff. I will make a post about things other than my I.T. class I promise. But for now this is what you get.

How do you get the data

Research, poll,

Numerical “2”,”10”

Validation

Correct type of data 

Ranges, lists, types

Process

Manipulating data into information

Formula, formatting data into a table

Testing

Is it what you want?

VCAA Problem Solving Methodology

Hello internet,

This post is about the efficiency of the  VCAA Problem Solving Methodology compared to other ones out there. I have done a comparison of the many others out there, making a pros and cons list of the VCAA technique which they teach us in VCE.

Pros Cons
-similar to   the ones I have found online

-has 4   stages and 11 activities divided between the stages so it is hard to miss   errors which could be made during the problem solving.

-it is   shorter than some which makes it easier to remember

-more detailed than some like the “How to Solve it” which comprises of understanding the problem, plan, carry out plan and look back on the solution, the OODA loop where the steps are to observe, orient, decide and act and is used in a military setting. The PDCA is Plan, Do , Check and Act

 -it could be harder to remember to order of the steps and there is no way to easily remember it like an acronym.

– Eight disciplines involves a team which can be useful when trying to solve a   problem

– Eight disciplines is also used throughout many industries which involve a lot of team collaboration   which shows it has evidence of its efficiency.

Overall I feel the VCAA Problem Solving Methodology is affective in its purpose which is to solve problems. It has a good balance of having a few steps and having them broken up into stages which makes it easier to remember.

Components of a Computer System

In my I.T. class we are learning about components of a computer system.

Here is what I have learnt so far…

  1. personnel: the developers, users and maintainers
  2. processes: the actions applied to the data by both the computer and personnel
  3. data: the raw material to be processed by the system
  4. software: provides access to hardware and enables hardware to carry out specific tasks
  5. hardware: physical components of a computer system

Our first project was to make a table representing something in computing showing its past, present and future stages. I picked storage because you always have to store stuff.
