Our task in week three's tute was to find the definitions for these three terms.

• ECU
• WS
  
• MS
  

Being in a new communications Lecture i figured they would be computer based or at least technological...
I thought I'd cheated but I didn't mean too! I typed ECU into Google and up popped the last classes posts from the tutorial. Turned out they'd done the same exercise.
Thus i've posted the link to a Craig's definition of ECU but i've also done my own research and found my own definitions.

Via the last classes blog! Didn't mean to i swear!

My double check...
ECU into google brought up all sorts...
Electronic Control Unit- http://autorepair.about.com/cs/generalinfo/l/bldef_160.htm
Extreme Close Up- http://www.acronymfinder.com/ECU.html
Error Correction Union- http://www.acronymfinder.com/ECU.html
European Currency Unit- www.investorwords.com/1655/ECU.html

Finally i got it...
It was my second step, Extreme Close Up. By Googling "Language of the Screen and ECU"
That was also how i found the other two... All about the Screen and Shot angles.
