Using a surge protector with computer equipment serves the essential purpose of protecting the equipment against electrical surges. An electrical surge can occur due to various reasons, such as lightning strikes, power outages, or sudden changes in electricity usage. These surges can deliver excess voltage to electronic devices, leading to potential damage to sensitive components, data loss, or complete failure of the equipment. A surge protector acts as a barrier that diverts excess voltage away from the connected devices, thereby safeguarding them and ensuring they operate safely and reliably.

On the other hand, enhancing internet speed, improving hardware performance, or managing power consumption are not the primary functions of a surge protector. While these aspects can be important in their own right, they do not relate to the protection against electrical surges, which is the fundamental role of a surge protector in a computing environment.
