Small UPS systems provide battery power for a few minutes to enable you to shut
down your computer.
USB

USB-compatible keyboard, mouse, joystick, scanner, set of speakers, printer,
broadband devices (DSL and cable modems), imaging devices, or storage devices.

hub that plugs in to your computer. USB devices can be connected and disconnected
while the computer is turned on, and they can also be daisy-chained together.

against electromagnetic interference, rather than relying on a metal sheath around
each pair of wires to protect against interference.
