Windows XP install requirement question

TeKniques

I have been studying for my A+ OS exam coming up and was going over minimum installation requirements for the different OS's and noticed that Windows XP has me kind of confused.

It says that 128 mb of ram is the recommended requirement, but says that 64 mb is the minimum but it may restrict some of the services the OS has to offer. So the question is, if not obvious.. which one is it?

Much obliged and thanks in advance.
