I'm surprised that C de-Avillez didn't break down the kernel part for
you. Anyway, starting at 3.0, the information can be broken down as:

3.0.0-23-generic-pae #39-Ubuntu
-  this is actually 3.0.0-23.39-generic-pae
The breakdown is:
<base kernel version>-<ABI number>.<upload number>-<flavour>
<base kernel version = 3.0.0>
<ABI number ((Application Binary Interface)) = 23>
<upload number = 39>
<flavour = generic-pae = generic kernel, pae enabled (allows a 32bit
kernel to access physical address space larger than 4 GB)>

#39-Ubuntu SMP Thu Jul 19 19:39:19 UTC 2012 i686 i686 i386 GNU/Linux
- Upload number 39,
- SMP (symmetric multiprocessing) multiprocessor, multicore enabled
- built date, time, year: Thu Jul 19 19:39:19 UTC 2012
- machine hardware name (i686) (sometimes called the hardware class or
hardware type)
- processor type (i686)
- hardware platform (i386) (means that the hardware is i386 backwards
- operating system GNU/Linux
