What voltage does a 586 system use? A. +12 volts B. + 5 volts C. + 8 volts D. +3.3 volts E. None of the above

The correct answer is: D. +3.3 volts

A 586 system uses a +3.3 volt power supply. This is because the 586 processor requires a +3.3 volt power supply to operate. The other options are incorrect because they are not the voltage that a 586 system uses.

• Option A is incorrect because a +12 volt power supply is used by some systems, but not by a 586 system.
• Option B is incorrect because a +5 volt power supply is used by some systems, but not by a 586 system.
• Option C is incorrect because a +8 volt power supply is not used by any system.
• Option E is incorrect because it is not a valid option.
