Hi this is part of my Activity Monitor

What does it mean that tiny apps and applets have such enormous Virtual Memory quantities?

Also I’m not sure if my Macbook is 64 bits, how can I know for sure? And if it isn’t is it still okay that some stuff is running at 64 bits?

That’s all… thanks for any help.
