When a CPU executes instructions as it converts input into output, it does so with __________.

• A. Control unit and the arithmetic logic unit
• B. RAM and ROM
• C. Cache and the motherboard
• D. Hard drive and RAM

Answer: (A)

The main idea is that the CPU carries out instructions through its two core parts: the control unit and the arithmetic logic unit. The control unit directs the flow of operations, fetches instructions from memory, decodes what needs to be done, and coordinates data movement inside the CPU. The arithmetic logic unit carries out the actual computations and logical decisions on the data, turning input into the desired output. Together, they perform the fetch-decode-execute cycle that transforms input data into results. Memory and storage components like RAM, ROM, cache, motherboard, or the hard drive aren’t the devices that perform the processing themselves; they hold instructions and data or help speed things up, but the execution work is done by the control unit and the arithmetic logic unit.
