The PC and PLC architectures share similarities such as a motherboard, memory, expansion slots, and which component?

Explanation:
The processor acts as the brain in both PC and PLC architectures, handling the fetch, decode, and execution of instructions and coordinating data between memory and I/O. That central role is why the processor is the shared component: it’s what runs programs and control logic on both systems. A monitor and keyboard are user interfaces for PCs, not fundamental parts of PLC operation, and storage, while present in many PCs, isn’t the defining shared element in PLCs.
