PS3 download resuming [ clarification ]

Hello, i'm really considering to buy a PS3 in the near future, and i have this question about downloading :

 When downloading a demo / firmware update / game etc. via PSN, are the downloads pausable and resumable, or they have to happen in a row ?

 Furthermore, if, for some reason, the machine is abruptly turned off during download, is the download resumable too in this case ?

Cheers.

Of course I will not. But i do live in the middle east, where average connection speeds are 128-256K, so it will take more than one session to finish an average 700 mb game demo.

And sometimes electricity is unstable so it just deconnects. I guess i'll solve this by plugging my (future) PS3 to a UPS.

Thanks for answering btw, and if someone can confirm whether firmware updates are resumable, that'd be great.

Cheers.
