Which tool can help protect computer components from ESD?

An antistatic wrist strap is specifically designed to protect computer components from electrostatic discharge (ESD), which can cause serious damage to sensitive electronic parts. When working on computer hardware, individuals can inadvertently build up static electricity through movement or contact with certain materials. The antistatic wrist strap safely grounds the individual, allowing any built-up static charge to dissipate harmlessly to the earth, rather than transferring to the components being handled. This is crucial in maintaining the integrity and functionality of delicate electronic circuits and components.

While the other tools listed may serve their own purposes in computer maintenance or repair—such as a magnifying glass for inspecting components, a screwdriver for assembly, and a digital multimeter for measuring electrical properties—they do not offer any protection against ESD. Thus, the antistatic wrist strap stands out as the vital tool in preventing damage from static electricity during hardware work.
