What Do You Call Your Digital Brain Helper?

What do you call your digital brain helper? You must have called it something! How do you get it to help you if you don't have a name to ask?

The one you have in your car, maybe linked through your Ford Sync setup, or the one that is with you throughout your house?
Or the one that sits inside your phone?

How do you work yours?

And what's its name? Hal? Computer? Barry? Baldwin? Zeus? Mary? Francesca? Minerve? or even just 'Oy you'!!
