I need to know the data bus width.

I know the Debian version number is stored in /etc/debian_version .

How do I find if the installed OS is 32 or 64 bit?

$ file /bin/true

That information is presented clearly.



How do I discover the CPU's bus width?

$ cat /proc/cpuinfo


The line
  address sizes	: 36 bits physical, 48 bits virtual
is clear.

I don't see the data bus width clearly identified.
Are the lines
  clflush size		: 64
  cache_alignment	: 64
pertinent?

TIA
