power conditioner
Also called a line conditioner, a device that sits between a computer and its power supply, typically a wall outlet. The power conditioner provides protection against surges in power just as a surge protector does, but a power conditioner also maintains a continuous voltage fed to the computer during temporary voltage reductions, such as a brownout. This is referred to as conditioning. Power conditioners also can filter EMI emanating from a power source and can smooth the rhythmic cycle of alternating current.

- power factor correction
Power factor correction (PFC) is a newer technology used in computer power supplies. PFC is applied to the circuits that include induction motors as a means of reducing the inductive component of the current and thereby reduce the losses in the supply. PFC has no effect on the operation of the motor itself. [Source: Adapted […]
- power line Ethernet bridge
A power line Ethernet bridge is a HomePlug device used to extend a LAN into a separate room using the existing electrical system in the building. An Ethernet cable from the network router is plugged into a bridge, which plugs into an AC wall outlet. In a separate room, a second bridge plugs into the […]
- power line networking
Power line networking uses power line communications (PLC) to connect computers using existing power outlets in the home, essentially transforming every electrical outlet in the building into a network connection. Power line networking is one of the cheapest forms of home networking and has a low start-up cost and minimal IT workload. And despite using […]
