How to Identify 32-bit or 64-bit Processors

In Linux, we have a command "cpuid" which gives complete information about the CPU, it's starts somewhat like this.

 

Intel-specific functions:
Version 00000f47:
Type 0 - Original OEM
Family 15 - Pentium 4
Extended family 0
Model 4 -
Stepping 7
Reserved 0 ....

 

Everything is present except whether the Processor is 32-bit or 64-bit CPU. Is it possible to find out based on the above info. wheter a CPU is 32-bit or 64-bit. If so, how? I have seen numerous sites, but haven't got exact info. of how this could be found thorugh an OS, either Windows or Linux.

 

Thanks in Advance.

 

Regards

Adarsh
