Hello,

take a look at the uname command:
Code:
markus@samsung:~$ uname -a
Linux samsung 3.5.4 #1 SMP Sun Sep 23 12:15:31 CEST 2012 x86_64 AMD Athlon(tm) II Dual-Core M320 AuthenticAMD GNU/Linux
markus@samsung:~$ uname -p
AMD Athlon(tm) II Dual-Core M320
markus@samsung:~$ uname -m
x86_64
As of question 4, you can run a 32bit kernel on a 64bit architecture, but not vice versa.

Markus
