PAE/SELinux

Mitch Frazier's picture

PAE, if supported by the CPU, allows x86 processors (and x86-64 processors running in 32-bit mode) to use more than 4 gigabytes of physical memory.

SELinux stands for Security Enhanced Linux, the name alone should tell you what its purpose is.

Mitch Frazier is an Associate Editor for Linux Journal.
