63. Which component is part of the system unit?
Answer: C
The motherboard is a component of the system unit.
The motherboard is a crucial part of the system unit, serving as the main circuit board that connects all components of a computer. It houses the CPU, memory, and connectors for other peripherals.
A) Printer
A printer is an external device used to produce physical copies of documents and images. It is not part of the system unit; rather, it connects to the computer as a peripheral device.
B) Keyboard
A keyboard is an input device used to enter data into a computer. While essential for user interaction, it is not a component of the system unit itself, as it connects externally.
C) Motherboard
The motherboard is indeed a fundamental component of the system unit. It contains the CPU, RAM, and provides connectors for other hardware components, making it an integral part of the computer's architecture.
D) Monitor
A monitor is an output device that displays visual information from the computer. Similar to the printer and keyboard, it is not part of the system unit but rather an external device that connects to it.
Conclusion
The motherboard is the only option listed that is a part of the system unit, as it integrates and facilitates communication between various internal components. In contrast, all other options represent external devices that play important roles in computing but do not reside within the system unit.
