CompTIA 220-802 Certification Practice Test

Answer: B - Electrostatic Discharge, or ESD, is a single-event, rapid transfer of electrostatic charge between two objects, usually resulting when two objects at different potentials come into direct contact with each other. ESD can also occur when a high electrostatic field develops between two objects in close proximity.

Key Takeaway: ESD is one of the major causes of device failures in the semiconductor industry. ESD can lessen the life-span of the components considerably. Always protect your PC components using anti-static mats, wrist straps, or bags.
