1.Analyze how the choice of port (e.g., USB vs. Serial) impacts the performance of a peripheral like a printer.
2.Evaluate the potential issues when connecting a keyboard, mouse, and monitor to a system unit using mismatched ports.
3.Assess how the Arithmetic Logic Unit (ALU) affects a computer’s processing speed in a gaming scenario.

- Answer: USB offers faster data transfer and power supply for printers, while Serial ports are slower and outdated, limiting efficiency.
- Description: A USB printer transfers large files quickly (e.g., 480 Mbps on USB 2.0) and powers itself, printing smoothly. A Serial port, at 115 Kbps, bottlenecks data, delaying jobs and needing separate power. This comparison shows why modern ports like USB dominate, aiding hardware selection skills.
2.
- Answer: Mismatched ports (e.g., PS/2 keyboard to USB-only system) cause connection failures, requiring adapters or replacements, delaying setup.
- Description: A PS/2 keyboard won’t fit a USB-only PC, stopping input. A VGA monitor on an HDMI-only system blocks output. These mismatches frustrate users and teach the importance of port compatibility, a practical hardware lesson.
3.
- Answer: The ALU’s speed in executing calculations (e.g., physics in games) directly boosts processing, reducing lag for smoother gameplay.
- Description: In a game, the ALU calculates object movements fast—e.g., a 3 GHz ALU handles millions of operations per second. A slow ALU bottlenecks this, causing choppy frames. This ties hardware design to performance, showing students its real impact.
