Which component is described as a continuous piece of metal surrounding the component to be hardened?

• A. A fraction of a millimeter
• B. Video Indicator
• C. Metallic Shielding
• D. Detector Array

Answer: (C)

Shielding relies on a continuous piece of metal forming an enclosure around the component to be hardened. This creates a barrier that blocks or attenuates external electromagnetic fields and also prevents the device’s own emissions from leaking out. The key is continuity—gaps, seams, or openings can let interference penetrate, so a solid, uninterrupted metal enclosure provides the best protection. The other options don’t describe a surrounding metal enclosure: a thickness measurement isn’t a component, a video indicator is just a status light, and a detector array is a set of sensors. Therefore, metallic shielding is the component that fits the description.
