The full form of UPS in the context of computer systems is Uninterruptible Power Supply
. An UPS is a device that allows a computer to keep running for at least a short time when incoming power is interrupted
. It commonly includes a battery that is kept charged and ready to supply power when needed
. UPS systems can be classified into two main types:
- Online UPS : This type of UPS continuously supplies electricity from its inverter without interruption, providing a seamless power source. However, it is more expensive than standby UPS and generates noise due to its cooling fan
- Standby UPS : Also known as offline UPS, this type of UPS instantly transforms into a battery when the power is turned off. During that time, the computer's power source is not operational, making it less suitable for continuous use
Some benefits of UPS systems include emergency power supply, protection against surges, increased battery life, and cost-effectiveness
. However, they also have some limitations, such as being dependable and having higher maintenance costs compared to uninterruptible power supplies
