Hello,

I often encounter these two notions: PAL - platform abstraction layer, and 
SAL - system abstraction layer. Is there is any conceptual difference 
between these two, or it's basically the same but spelled out in different 
words? I've read wiki and other resources about PAL and understand its 
concept and intention, but not sure about SAL -- what I've met so far is 
part of SDK for communications devices, and basically do some sort of 
abstraction of underlying hardware, not only OS. Anyway this is my 
understanding, and it might be incorrect, would be glad to hear some 
comments.

Thanks.

Mark
