Question 285Electricity & Electronics - QMED

The correct answer is D) printed circuit board. PCB is a common abbreviation that represents a printed circuit board, which is a fundamental component in electronic circuitry. A printed circuit board is a flat, rigid or flexible material that serves as the base for mounting and connecting electronic components using conductive pathways, or "traces," etched from copper sheets laminated onto the board. The other answer choices are not accurate representations of the PCB abbreviation. "Pulse coded binary," "personal computer bits," and "poly-coated braid" are not standard terms used in the context of electronic circuitry.
