When examining what goes into computer and electronic hardware, you find an intricate assembly of physical materials, microscopic electronic circuits, and mechanical parts. Inside a computer hardware case, for instance, you will find silicon microchips etched with billions of microscopic transistors, copper wiring tracks printed onto fiberglass-epoxy circuit boards, aluminum and copper heat sinks designed for thermal dissipation, magnetic storage platters or flash memory memory chips, gold-plated connector pins, and plastic or steel structural chassis enclosures. Each element is engineered to conduct electricity, process electrical signals, dissipate generated heat, or provide sturdy physical protection for delicate components.
