What does PCB stand for?
-
A.
Processing Circuit Board
-
B.
Printed Circuit Board
-
C.
Peripheral Connection Bus
-
D.
Primary Control Board
Correct Answer:
B. Printed Circuit Board
Explanation:
PCB stands for Printed Circuit Board. It is a fundamental component in electronics consisting of a non-conductive substrate, typically fiberglass, with conductive pathways etched or "printed" onto its surface. These copper tracks provide the necessary mechanical support and electrical connections for various electronic components like resistors, capacitors, and integrated circuits. This technology replaced point-to-point wiring, allowing for more compact, reliable, and cost-effective manufacturing of electronic devices. Therefore, the correct expansion of the acronym is Printed Circuit Board.
