Final answer:
The correct missing structural component of the CPU is the Arithmetic Logic Unit (ALU). Also, resistors are the circuit elements that dissipate power, and information is the most important commodity in a postindustrial society.
Step-by-step explanation:
The major structural components of the CPU are control unit, register, CPU interconnection, and Arithmetic Logic Unit (ALU). This question seems to be missing the correct option in the provided choices (a-d), as memory, power supply, input devices, and output devices are not parts of the central processing unit (CPU) but are rather components that interact with the CPU. The ALU is essential for performing computations and logic operations within the CPU. When discussing circuit elements that dissipate power, the correct answer is resistors. In a postindustrial society, the most important commodity is information. Integrated electric circuitry is at the core of modern electronic devices such as computers and cell phones, while high-power electric power transmission requires specific electric circuitry for its function.
