What are the advances of Kernel 2.6 over Kernel 2.4.

Yes, Thats exactly what I want to know. I have been asked this in an interview and I had put up a blank face.

Security Enhanced Linux (SELinux) and Mandatory Access Control (MAC)

Monk, nice list.

I think take a look at The Wonderful World of Linux 2.6 http://www.kniggit.net/wwol26.html FTFA "Although it seems like only yesterday that we were booting up our first Linux 2.4 systems, time has ticked by and the kernel development team has just released the 2.6 kernel to the public. This document is intended as a general overview of the features in the new kernel release, with a heavy bias toward i386 Linux. Please also be aware that some of the "new" features discussed here may have been back-ported to Linux 2.4 after first appearing in Linux 2.6, either officially or by a distribution vendor. I have also included information on a handful of cases where a new feature originated during the maintenance cycle of Linux 2.4, and those will be marked as appropriate in the text."
