Why is it important to ground both computers and network devices?

• to ensure that the power supply is limited to an output of 110V DC
• to facilitate the flow of current from the power supply to the computer case
• to provide a path of least resistance for stray current
• to ensure that both the power supplied and the power used is in sync with the ground voltage
  

  Answers Explanation & Hints: In the event of stray current being generated by a fault within the computer, the ground will provide a path of least resistance for the current to flow harmlessly away.
