PAE (Physical Address Extension) is a feature which allows 32-bit x86 processors to access more than 4GB of memory (RAM). As of Ubuntu 12.04, the PAE kernel is the default for 32-bit installations. PAE is supported by all Intel processors since the Pentium II and by AMD since the Athlon; notable exceptions are some Intel Atoms and some Pentium Ms.
