During this testing testing team validates whether the 
application is build is customer expected plotform or 
not.or whether the application is capabilly of runing or 
not in different environmentes.----software configuration 
or hardware configuration.

Whether our Application supports all customer expected 
Platforms(operating systems,browsers) or not?

Compatability testing means testing the application build 
on different platforms whether the application build is 
able to run on different platforms or not.

platforms means O/S,Browsers,Compilers,Other system 
software.

There are 2 types of Compatibility testing...

Forward Compatability
Backward Compatability.

suppose executing a build on unix o/s which is developed in 
Microsoft Languages like VB.Forward compatability

executing the lower versions of s/w on higher versions of 
platforms......Backward compatability.

enjoy......
