It depends on the application, and on the implementation of the UPS. Some UPS devices function as an AVR by boosting the output voltage when the input voltage sags. A UPS will also help you during a complete power outage, which an AVR will not. A UPS however has batteries which need to be periodically replaced. An AVR does not, which means less maintenance.
if you are reffering to Vcc than it means- It is the positive power supply used for TTL gates it is nothing but simple dc power supply. if we use CMOS than we use Vdd for indicating power supply these are method for indicating power supply.
A transformer does not use a filter. You may be asking about the use of a filter in a power supply. A power supply uses a filter to change pulsating DC from the rectifier into smooth DC for the circuits that the power supply powers.
Yes. Depending on the design, the power supply can provide any voltage desired.
Answer for countries in Europe and other world areas running a 50 Hz supply service.AC power supply is 230 v supply used in our homes for switching on fans, bulbs etc. where as DC power supply is used for switching on our laptops, charging our mobiles phones, i pods etc.
UPS = Uninterruptible Power Supply
You can't "calculate" it...

As long as the UPS has power. UPS's have different run times.

Use a power supply tester. You can get them on ebay for under $5.
