256 MB enough?

Hey, guys

I am going to make a computer out of scrap and donate it to charity, but I’ve got this 256MB DDR Memory chip, is this enough to run windows XP on? It is only going to be used for social-networking and surfing on the net. Its not going to be used as game-computer. To make a long story short: It’s not gonna be used for heavy-duty tasks and programs.

Is 256 MB enough?

Thanks in advance
