[Year 12 IPM] OT: Unit 2 IT study design

[Murray O.]

Hi Mark
A data entry screen is a method of acquiring data and what is entered into
it, via an input device eg keyboard, is the input.

At times I struggle with the acquisition / input concept

One example that confuses me is a scanner is an input device but what about
the E - tag system. Is the scanner an input device or an acquisition device?

IT Unit 2
Outcome 1
Key Knowledge dotpoint 2 (at the end) refers to:

'method acquiring (sic) data (for example, sensors, data-entry screens)'

Quibble 1 - "method acquiring data" does not make sense.

Quibble II (Revenge of the Quibble)- The punctuation seems to collapse 
in this para: the commas before "nature of output" and "method 
acquiring" should surely be semicolons.

Argument - Would not "data entry screens" constitute input rather than 
acquisition?  Sure, they may be gathering new data from people, but if 
they are entering the data into the system at the same time, it would 
surely count as input.

Any opinions?  I've finished reports and have time for a good quibble  :-)
