A momentary gap in power occurs between the loss of AC power. UPS stands for Uninterrupted Power Supply. It works like a battery and a surge protector together. It helps computers and other electronic equipment to function for any time period, without losing connection. SPS stands for Standard Power Supply. Compared to UPS, SPS is not as effective. While they both have a battery, the SPS battery provides power only when AC power is lost to the computer. before this can be implemented, the SPS must detect that the power is out. Then, it can switch the battery over to the supply.

UPS means Uninterruptable Power Supply, and SPS means Standard Power Supply. It might be confusing to know the difference between the two in the beginning, but basically, SPS is known to be a power surge protector while the UPS will work as a continuous power supply. The UPS will be in charge of providing the right supply of electricity needed to ensure that the equipment will not shut down unexpectedly, especially during a power shortage. The SPS is considered to not be as good as the UPS as it can only provide a very limited power supply that will just be available when it is needed. When it comes to pricing, SPS is also considered to be less expensive as compared to UPS.

In order to understand the difference between UPS and SPS, you should first know what they mean. UPS stands for Uninterruptible Power Supply. SPS, on the other hand, stands for Standby Power Supply. SPS is known to have a battery that will also work the same way as the UPS, but the main difference is that UPS is known to be more powerful.

The battery will be able to provide the power that is needed if in case the AC loses its power. Take note that between the two, most people know that the UPS is more effective as compared to the SPS, but it will still depend on you which one you would like to get.

A momentary gap in power occurs between the loss of AC power.

An SPS is known as Standby Power Supply and a UPS stands for Uninterrupted Power Supply. The correct answer is C because SPS supply kicks in only when there is a power cut and it takes a few moments for the reserve power to activate. UPS, on the other hand, continues working without interrupting the current flow and substitutes power immediately after a cut.

A UPS is short for an Uninterrupted Power Supply. `In business, an outage can cost an organization dearly. A UPS is a power inverter, a surge protector and a battery all in one. It enables computers, electrical and telecommunication equipment to keep functioning for a given amount of time, without loss of connection. It will supply the optimum power for a computer or electronic device at all times.

Some would say that an SPS (Standard Power Supply) is less effective.. An SPS contains a battery like the UPS, but instead of providing constant power, the battery provides power to the computer only when it loses AC power. The SPS must detect a power-out condition first and then switch over to the battery to supply power to the computer. In practice, this means that the outage has already occurred, and in business, the problems will already be in progress.

The battery is only used when the ac power fails-2. they are on all the time-3. they are far less expensive-when an sps is used there is a momentary gap, usually about 1ms or less, between when the power goes off and when the sps starts supplying power. spss are also less expensive and are not used at all times. 12. a, b, c, d. when turning on a system that shows no signs of life you must consider all of these as potential problems. 13. a, c. all processors require a heat sink. a heat sink is a finned metal device that radiates heat away from the processor. an active heat sink (a heat sink with a fan) is required for adequate processor cooling on current systems. some older systems used a specially designed duct to direct airflow over a processor with a passive heat sink (a heat sink without a fan). most motherboards northbridges use passive heat sinks. 14. a. thermal compound (also known as thermal transfer material, thermal grease, or phase change material) provides for the best possible thermal transfer between a component (for example a cpu) and its heat sink. this prevents cpu damage. the fan and adapter cards should not have thermal compound applied to them. as a side note, most northbridges do not have fans.
