- Describe the functions of the ALU and Control Unit in a computer’s block diagram.
- Answer: The ALU (Arithmetic Logic Unit) performs calculations and logic operations, while the Control Unit directs the flow of data and instructions.
- Description: The ALU adds numbers or compares values, like in a calculator app. The Control Unit acts like a traffic cop, telling the CPU what to do next—e.g., fetch data from memory. Together, they’re the brain of the system, shown in a block diagram.

- Answer: Data signals move from input to ALU for processing, then to output, while control signals from the Control Unit manage the process.
- Description: When you type, data signals go from the keyboard to the ALU to process (e.g., spell-check), then to the monitor. Control signals ensure each step happens in order, like a conductor leading an orchestra. This flow is key to understanding hardware operation.
