61. Which component is part of the system unit?
Answer: D
The motherboard is a component of the system unit.
The motherboard is an essential part of the system unit, serving as the main circuit board that connects various components of a computer, including the CPU, RAM, and storage devices.
A) Printer
A printer is an external peripheral device used for producing hard copies of documents and images. It is not a component of the system unit itself, as it does not reside within the computer's casing or contribute directly to its core functions.
B) Monitor
A monitor is another external device that displays visual output from the computer. While crucial for user interaction, it is not part of the system unit, which encompasses only the internal components of the computer.
C) Keyboard
A keyboard is an input device that allows users to enter data into the computer. Similar to the printer and monitor, it is considered an external peripheral and does not form part of the system unit.
D) Motherboard
The motherboard is the primary printed circuit board within a computer system. It houses the CPU, memory, and other crucial components, making it a fundamental part of the system unit.
Conclusion
The motherboard is definitively the correct answer as it is the only option that is an integral part of the system unit. Other options, such as the printer, monitor, and keyboard, are external peripherals that do not reside within the system unit itself, thus failing to meet the criteria of being a component of the system unit.
