Macbook Air: Model of 2013 or 2014? New apple user here,

I found this Macbook Air model:
http://www.ispot.ma/index.php/mac-15/macbook-air/macbook-air-md760.html

When I did a search about the Serial Order (MD760F/A), I couldn't find it!

My Question:
How to identify this model? 

Thank you in advance!
What you have here is a model number, not a "Serial Oder".

You can look up Mac model numbers here, for example:
