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

jsimmo:
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*
