How to find OS and harware architecture
I want find the how many bits my OS and my hardware is
In one machine "uname -a" gives me below output
Linux hqperf-amd04.us.oracle.com 2.6.9-22.214.171.124.2.ELsmp #1 SMP Wed May 2 15:06:32 PDT 2007 x86_64 x86_64 x86_64 GNU/Linux
in other box, it gives me as,
Linux hqperf-amd03.us.oracle.com 2.6.9-126.96.36.199.2.ELhugemem #1 SMP Wed May 2 15:04:06 PDT 2007 i686 athlon i386 GNU/Linux
can some body explain ...
1. How may bits my OS is?
2. how many bits my Hardware is?
3. Can I install a 32 bit OS on 64 bit Hardware?
