Title: Cloud's ITA questions
Post by: danieltennis on November 17, 2008, 02:47:29 pm
Hey guys,
I havent been studying or doing any work for IT all year and I need serious help. I've got a few questions to ask.

1/ When establishing a clients needs when creating an information product, there are contraints. List three main categories for the constraints.

2/ Select one the answers you gave in question 1 and explain what constrait means.

ii/ Describe clear terms the function of a Gantt Chart and PERT chart outlining the difference between them.

Thanks.

Are you taking IT:A for 2009?

I'll change the order a bit.

2. A constraint is to restrict/hold back (cf. 'constrain'). It means something that creates a limitation on a system.

1. Things that could limit a system include:
- cost ('economic')
- technology available ('technical')
- how things are done normally ('operational')
- the external environment ('social')

3. Use Wikipedia :P there's a fairly clear explanation on both.

Yes, I am.
Another question.

1/ If information is to be used for a particular purpose, it is very important to ensure that it is of high quality. Give three tests you could apply to data to ensure that it is of a high quality.

2/ Write the output produced by this program.
words = 'this IS NoT EvEN'
Print words.title()
Print words.replace("IS", 'was')
Print words.upper()
Prints words *2

3/ What is Reverse Osmosis?

Thanks

A Gantt chart is like a timeline that shows when tasks need to start and finish and what resources will be needed at each stage.

A PERT chart is like a map laying out all the tasks and how they relate to each other, especially which tasks cannot start until other tasks have been completed.

*Gantt charts are better at showing how tasks use time. PERT charts are better at showing task dependencies.

1/ Test the final solution against the initial requirements (purpose). If it meets these requirements, the solution is of high quality.

2/ I doubt IT:A would do pseudocode, let alone what appears to be a Basic-like programming language.

3/ wut? *points to Chemistry forum*

It's not in the 3/4 course, but it was in last years 1/2 for me [i'm pretty sure it is in the study design].

Yeah, because year 11 IT is a mix of SD and APPs

Another question.

ii) Jay wants customers to order her jewellery online. Select and justify an effective way of backing up Jay’s
files. Ensure that your answer refers to one or more of the following: complete backup, differential backup
and incremental backup.

1/ What is a primary key? Thanks

Complete (full) backup: Backup everything onto a separate medium

Differential backup: Consists of an initial full backup, then any changes made are backed up onto one separate medium (so you have stored one full backup, and another with any changes made after the full backup)

Incremental: Also consists of an initial full backup, then any changes made are backed up onto several media (so you would have a stored a full backup, plus each change made is stored on a separate medium. For example, after the initial full backup, you might make an incremental backup each month, March 2008, April 2008 etc.)

Take your pick, but don't just choose full backup.

1/ A primary key uniquely identifies a record in a database. (This is all you need to know, really)

Ok i don't understand what they mean by this question.

Borak Enterprises are looking at the establishment of a new head quarters in Hong Kong, replacing the
existing office in Melbourne. The Human Resources Department is engaging a consultant to look at how
this will affect the current levels of staff.
Select the appropriate response from those listed
A. This is a tactical and operational decision
B. This is a an operational and strategic decision
C. This is a strategic and tactical decision
D. This is a strategic, operational and tactical decision.

Yeah these are always tricky to get your head around. Here's a table I made this year for my notes:

Type of decisionMade byTime frameDescription and examples
StrategicOrganisation’s top/senior managers, e.g. CEO or president.long term (years)Usually expensive and affect the whole nature of the organisation. Examples of strategic decisions include closing store branches or diversifying into new areas. These decisions are usually based on highly summarised information.
Tacticalmiddle-managers, e.g. regional manager, state manager of a national organisation.weeks/monthsMade to implement strategic decisions, i.e. tactical supports strategic. Examples of tactical decisions include hiring extra staff or improving staff training. These decisions are usually based on summarised information.
OperationalStore managers or sales assistantsDay-to-day basisDeal with non-management workers and keep the organisation working and productive. Examples of operational decisions include on-the-spot price reduction of a product or deciding whether a staff member can have time off work. These decisions are based on raw data or detailed (not summarised) information.
Back to the original question, "...establishment of a new head quarters in Hong Kong, replacing the existing office in Melbourne". This is obviously a strategic decision as it is expensive and large in nature.
This part: "Human Resources Department is engaging a consultant to look at how this will affect the current levels of staff" is most probably a tactical decision as it is just one department of the organisation (it is also dealing with staff performance/attitudes etc so it fits nicely under tactical).

So the answer should be C, strategic and tactical.

Similar question in this year's ita exam. Make sure you know this for this year and next.
New headquarters are MAJOR decision a company can make therefore there needs to be a STRATEGIC decision here. From this, you can take out A.
The Human resource department = tactical. Therefore eliminates OPERATIONAL. This leaves the answer as C. It is not D -note the wording. No decisions made by operational.

You don't need to have done Units 1 + 2, though it may help.

I never did 1 + 2 personally and nor did most people I know who did IT:A this year. In fact, I've found that the ones who went direct to 3 + 4 tend to do a bit better (whether this is self-selection bias, I do not know).

So there is hope for the people picking up I.T Apps..woooott :D :D

Hey,

In the context of a school library information system, can you provide an example of each component?

The components are:
Software
hardware
data
personnel
procedures

Just need to know whether I'm correct. Thanks.

Software: Database software (Access, Filemaker)
Hardware: Computer, barcode scanner
Data: Student name/details, book info (Title, author, genre etc.)
