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

• A. To prevent overheating
• B. To provide a path of least resistance for stray current
• C. To enhance signal transmission
• D. To boost performance

Answer: (B)

Grounding both computers and network devices is primarily necessary to provide a path of least resistance for stray current. This safety measure is crucial for several reasons. When electronic devices are not properly grounded, static electricity or electrical surges can build up, potentially causing damage to sensitive components. By grounding devices, any stray current is safely directed away from the equipment and into the ground, minimizing the risk of short circuits and electrical shock.

This grounding also helps in stabilizing the voltage levels within the devices and networks, providing additional protection against spikes or transients in electrical power. Overall, grounding is a fundamental practice in electrical safety and device protection, which is vital in ensuring the proper functioning of computers and network devices.
