5. Which component is part of the system unit?
Answer: B
Motherboard is part of the system unit.
The motherboard is a critical component of the system unit, as it serves as the main circuit board that connects various components of the computer, including the CPU, RAM, and other hardware.
A) Monitor
The monitor is not part of the system unit; it is an external device used to display output from the computer. While essential for user interaction, it operates independently of the system unit's internal components.
B) Motherboard
The motherboard is indeed a fundamental part of the system unit, providing the necessary connections for the computer's hardware components and enabling communication between them. It is integral to the computer's functionality.
C) Keyboard
The keyboard is an input device used to enter data into the computer, but it is not part of the system unit itself. Like the monitor, it connects externally to the system unit rather than being housed within it.
D) Printer
The printer is an output device that produces hard copies of digital documents. It is not included in the system unit since it operates externally and serves a different purpose than the internal hardware components of the computer.
Conclusion
The motherboard stands out as the only component listed that is part of the system unit, as it is essential for the integration and operation of the computer's internal parts. In contrast, the monitor, keyboard, and printer are all external devices that facilitate interaction with the computer but do not reside in the system unit itself.
