Installation help needed(64 bit or 32 bit)

Hi ,
I have to install Oracle Enterprise linux 64bit version on my machine.

How would i determine whether my system is compatible for 64 bit version.

What is difference between 64 bit version and 32 bit version?

I heard that 64 bit version are suitable for machine with ram more than 4 gb is it true?

Which OS ?

Code:
grep flags /proc/cpuinfo

lm means Long mode - 64 bit CPU
Real mode 16 bit CPU
Protected Mode is 32-bit CPU

[piyushs@piyushs amit]$ grep flags /proc/cpuinfo
flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm lm

Thanks but the machine is currently having windows os installed on it .

How would i check the cpu information in windows.

One way: right click on "My Computer" -> Properties. Below the registration information should be a field telling you what CPU you've got. Now search the web with that information.

Or: Try to boot the system with a 64bit Linux (eg. a LiveCD). If it works, you've got a 64bit CPU, otherwise you'll get an error message.

Okay, let's apply some common sense here.

Searching the web for that processor returns the Wikipedia entry for it. Right there in the first line (emphasis added)

what do you think the 2 flags I've set to bold mean?

Most probably.

Although I experience a slight discomfort at the facts that a) you have no clue what hardware you're using and b) fail at applying basic thinking to the facts presented to you.
