What are the primary functions of an uniteruptable power supply?
The primary function of an uninterpretable power supply, or UPS, is to continue to give an electrical device, such as a computer, power when normal house power is disrupted. Normally the UPS only provides enough power to use the device long enough to properly shut it down.
How do computer users protect their computers from too much electricity?
To protect a computer completely from electrical problems you would have to keep it unplugged. Unfortunately this makes it useless. Using surge protection on the power supply is a simple and relatively cheap protection from spikes in the power supply. A UPS or uninteruptible power supply can be set up to allow the computer to run for a period of time after a breakdown in the power supply. These are more expensive the longer they can supply power, and are often set up to supply power for just long enough to do a save and tidy shutdown of the computer.
What part of the computer holds data for long periods of time even when there is no power to the computer?
Secondary Storage or Hard Drive
Why do you lose unsaved data on you computer during power failure?
There two types of memories in cpu .1.temporary ,2.permanent. Whenever doing any work with out saving the data then it store in temporary memory until the shutdown the computer or power cut.
How long should a computer power cord last?
It really depends on the computer model. I think what ur trying to ask is how long does the battery last, 6 to 8 hrs I think.
How long will my desktop computer stay running on just dc power supply alone?
Your computer can run as long as there is a power supply. As long as the power is on you should have no problem
What the use of computer UPS?
A computer UPS (Uninterruptible Power Supply) is designed to provide power to a computer system if normal power fails. The length of time a UPS will support a computer depends on the capacity of the UPS and the draw of the system being supported. Properly configured and installed, most systems will monitor the UPS and begin a normal shutdown when notified by the UPS that a power outage is in process. Some are large enough to maintain computer operations long enough for backup power generation to come online.
1 How long does a power supply retain power after the computer is turned off?
A computer power supply has capacitors and can maintain power for a along time. See:http://en.wikipedia.org/wiki/Capacitor#Hazards_and_safety
What component is key to a long life for a computer?
Good power supply and good cooling.
What is the most common problems with PC power supplies?
The most common problem lies with the user rather than the power supply itself.The computer user hardly ever thinks about his power supply so long as it works.Therefore they'll overburden the power supply by adding hard drives until it's overwhelmed.When you add power hungry componenents to your computer you have to consider whether or not you have adequate power.WHen you have a problem with your power supply in general your computer stops working and you have to spend 30$ for another.
What is a ups used for in computers?
A UPS (Uninterruptible Power Supply) allows a computer to keep operating in the event that main electrical power is loss. This may allow just enough time to save any work and shut down safely, or it may provide enough power to keep operating for a long period of time until power can be restored. A UPS device will also contain a surge suppression device to protect against power surges, but you can get these without purchasing a UPS.
Can you get info off computer with failed power supply?
Yes, as long as the rest of the computer is still intact (eg. motherboard, hard drive etc.) You can either: Get a new power supply for the computer and everything should work as normal (power up and everything) Take out the hard drive and put it into another computer to recover the data (there are many ways of doing this, try googling it - that should help.
Is there a 5-Phase Uninterruptible Power Supply?
AnswerCheck your terminology. Do you mean 3 phase (3 hot wires, a neutral wire, and a ground wire) power that would be used in a commercial building? If so, yes they are made. Most of the ones I've seen (I've only really looked on eBay) were large, expensive models designed so suppost an enormous load just long wnough for a generator to start. You can probably find ones designed for longer run times, though.There has no 5-phase power supply available in the market.

What frequently ensures that no work will be lost if there is a power outage or you experience computer problems.?
A UPS or Uninterruptible Power Supply is a device that contains a battery and will protect your computer or server from both power surges, and brown outs. A brown out is when the power drops below the required voltage and a UPS helps by using power from it's internal battery to supplement the power from the wall outlet and keep a constant stream of current to the attached equipment. Secondly, most UPS' will have a communications cable that connects to your computer or server. You'll install software that let's your computer talk to the UPS. When the power goes out, the UPS will turn on and tell the computer that there is a power outage. The computer will then start a timer letting you know how long you have before it will automatically shut down. The bigger the UPS, the more time you'll have. This is the time to save your work (which you do frequently anyway...right??) because once the UPS battery gets low, it will automatically power off your computer to protect it, whether you've saved or not.
Is it unsafe to work on computer when electricity is being supplied through a generator?
It is unsafe both for the computer and you to work on a computer while it is plugged into a power supply. If you mean simply to use the computer, then no, it is perfectly safe as long as the generator doesn't generate more power than the computer can use. (probably 120 V)
Yes as long as the hard drive has its own power supply and not powered by the USB port.?
Yes as long as the hard drive has its own power supply and not powered by the USB port.
