what is the difference between these master

Master of Engineering in Electical and Computer Engineering vs
Master of Engineering Science in Electical and Computer Engineering

I think it depends where you are from. BUt where I am from, one degree involves writing a thesis and the other involves taking courses. One is more for research and the other is more for work (not that research isn't work but I hope you understand what I mean lol).

yes i get it now
it is talking about tow types
1 - courses based on
2 - Research with Prof. Based on.

thanks too much
