UPS Full Form

UPS stands for Uninterruptible Power Supply. It is a device that supplies power to devices for a fixed amount of time without stopping even when there are problems occurring with utility power and other power sources. When power failures such as power outages occur, computer devices such as servers and workstations may break down, leading to various problems such as the loss of important data and program malfunction
