UPS will prevent data loss during power outages as well as line conditioning -smoothing any spikes or dips and protecting against electrical noise. In a business environment they can be a lifesaver.
I just had a huge network setup in my new business with 25 computers. There is a server room and all that with sufficient backup protection. Now I am being told to buy a battery backup unit for each of the computers on the network in order to protect against not only power surges, but also the quick zaps of high or low electric power (I'm sure there are better words for that). I thought we just needed surge protectors with 2900 joules or so. Please advise. Thanks
