[sushilkumar]

I am not Computer literate. I have installed Ubuntu on my home PC as it will avoid any virus.

Please tell me how to know which of two (32bit 0r 64 bit) I m using.

( I have tried to find answer in this forum and else where but could not find)

Thnx in advance

open a terminal and type:

uname -a

if you see x86_64 you're using 64bit

if it's i686 then you're 32bit.

oh, and the giant text and different colors are really annoying, you're more likely to get better help if you just use the default text.
