Answer:
c. By protecting against voltage spikes.
Step-by-step explanation:
Voltage spikes, also known as power surges, are sudden increases in electrical voltage that can occur due to lightning strikes, power grid fluctuations, or electrical malfunctions. These voltage spikes can be detrimental to electronic devices, including computer systems.
Here's how a surge protector helps maintain a computer system:
1. Diverting excess voltage: When a voltage spike occurs, a surge protector detects the excessive voltage and diverts it away from the computer system. It acts as a barrier between the power source and the computer, preventing the harmful surge from reaching and damaging the sensitive components of the system.
2. Absorbing excess energy: Surge protectors are equipped with components, such as metal oxide varistors (MOVs) or gas discharge tubes, which absorb excess energy from voltage spikes. These components redirect the excess energy safely to the ground, protecting the computer system from potential damage.
3. Protecting against electrical fires: In addition to safeguarding the computer system, surge protectors also reduce the risk of electrical fires. By preventing excessive voltage from reaching the computer, surge protectors help prevent overheating or short circuits that could lead to fires.
4. Extending the lifespan of equipment: By shielding the computer system from voltage spikes, surge protectors help prolong the lifespan of electronic devices. Sudden voltage surges can cause irreversible damage to components like the motherboard, hard drive, or power supply unit. Using a surge protector ensures that the computer system remains protected and functional.
It's important to note that while surge protectors provide protection against voltage spikes, they do not prevent power outages or regulate internet speed (options A and B). Power outages can still occur if there is a complete loss of electricity, and internet speed is typically regulated by the internet service provider and network infrastructure.
In summary, a surge protector helps maintain a computer system by protecting against voltage spikes. It diverts excess voltage, absorbs excess energy, protects against electrical fires, and extends the lifespan of electronic equipment.
