When I installed F11 on my Toshiba laptop, it installed the PAE version

My laptop only has 3 GB installed. Can anyone explain the pro's and
con's of using the PAE version of Linux kernel instead of the non-PAE
version?
The real reason to use PAE is to get the security benefit of the NX feature.

Would the PAE version of the 32-bit Linux Kernel see 4 GB of memory if
it was installed where Vista 32-bits only sees about 3GB? For that
matter would the non-PAE version see the full 4 GB?
Depending on the laptop that may or may not buy you 4GB capability, there are
BIOS and hardware issues which I'm not about to try and remember, much less
explain. If you hardware and BIOS support 4GB, yes you will use it with PAE.
