communication.
brownout - Answer A drop in the power supply, but not a total loss of power.
burner - Answer An optical drive so named because it employs a laser capable of intensities stronger
than what are used to read discs. It uses the laser to write, or "burn," content to the disc.
bus - Answer A set of signal pathways that allows information and signals to travel between
components inside or outside a computer. A computer contains three types of buses: the external bus,
the address bus, and the data bus.
