Numerous extended peripherals may be added to a computer system to increase its utility. Among these is the MIDI/sound system. This system allows the user to input music and sound effects and hear the results on a speaker set. Also available are network peripherals, which enable the user's computer to communicate with other systems through modems and local area network links. Tying these peripherals together are a variety of |cables| and |connectors|. To protect the components are the |surge suppressor| and the backup |power supply|, which guard against power fluctuations capable of damaging sensitive electronics.
