16. Which component is part of the system unit?
Answer: B
Motherboard is part of the system unit.
The motherboard is a crucial component of the system unit as it houses the CPU, memory, and other essential parts, facilitating communication between all components within the computer.
A) Keyboard
The keyboard is an input device used for typing and interacting with the computer, but it is not part of the system unit itself. The system unit specifically refers to the main housing that contains the core components necessary for the computer’s operation.
B) Motherboard
The motherboard is indeed part of the system unit. It serves as the main circuit board that connects all hardware components, allowing them to communicate and function together effectively.
C) Printer
The printer is an external device used for producing hard copies of digital documents. It does not reside within the system unit and therefore is not considered part of its components.
D) Monitor
The monitor is an output device that displays visual information from the computer. Like the printer, it is an external device and does not form part of the system unit, which contains internal hardware components.
Conclusion
The motherboard is definitively the correct answer as it is the central component within the system unit that connects and manages all hardware interactions. In contrast, the keyboard, printer, and monitor are all peripheral devices that play supportive roles but do not reside inside the system unit itself.
