What is the RAM limitation of Ubuntu linux?

Question

what is the ram limitation of ubuntu linux 32 bit? and also of windows xp and vista 32 bit if you know. thank you!

Answer 1

There are lower limits on each. That is to say that they would not work on RAM , BELOW  a certain amount. Ubantu, XP & Vista have all different lower limits depending on what OS you have & what version(of Ubantu or SP of M$) are you running. The upper limit nowadays is limited pretty much to the maximum a mainboard can support.
