61. Which component is part of the system unit?

Answer: D

Explanation:

The motherboard is a component of the system unit.

The motherboard serves as the main circuit board in the system unit, connecting all components of a computer and allowing them to communicate with each other.

A) Printer

A printer is an external device used to produce a physical copy of digital documents. It is not part of the system unit, as it operates independently and connects to the computer externally.

B) Monitor

A monitor is also an external device that displays visual output from the computer. Like the printer, it is not included in the system unit, as it functions as a peripheral display device.

C) Keyboard

While a keyboard is an essential input device for interacting with a computer, it is not housed within the system unit itself. Instead, it connects externally to the computer to facilitate user input.

D) Motherboard

The motherboard is the central component of the system unit, providing the necessary connections for the CPU, RAM, and other internal hardware. It plays a crucial role in the overall functioning of the computer.

Conclusion

The motherboard is definitively the correct answer as it is a vital component located within the system unit, unlike the other options which are external devices. Understanding the role of the motherboard helps clarify the distinction between internal components and peripherals in a computer system.
