Almost all computers, computer peripherals (printers, modems, scanners, etc.) and home entertainment products (stereo, DVD player, televisions, etc.)draw an idle electrical current even after they have been turned off. Some devices still draw the same amount of power even when turned off. To alleviate this, the device needs to be physically unplugged from the wall. Using a power strip allows multiple devices to be plugged into one unit. Rather than having to unplug multiple devices, you only need to unplug (ad plug back in) the power strip in this case making it a much easier process that you are more likely to remember.
