Shield

A shield is a protective barrier designed to block or deflect harmful elements such as physical threats, radiation, or electronic interference. It can be made from various materials like metal, fabric, or specialized compounds, depending on the type of protection needed. For example, a car’s shield protects occupants from debris, while electronic shields prevent data from being intercepted. Shields are used across many fields—from personal safety gear to cybersecurity—serving as a safeguard to maintain safety, integrity, and functionality by preventing damage or intrusion.
