12. Which hardware component contains soldered parts and slots for other pieces of hardware that can be removed?
Answer: D
The motherboard contains soldered parts and slots for removable hardware components.
The motherboard is the primary circuit board in a computer, featuring various soldered components such as the CPU and memory, along with slots for removable hardware like graphics cards and RAM.
A) System clock
The system clock is an essential component that helps regulate the timing of operations within the computer. However, it does not contain soldered parts or slots for removable hardware, making it incorrect in this context.
B) Hard drive
The hard drive is a storage device that retains data but does not contain soldered parts or slots for additional hardware components. It is typically a standalone unit that connects to the motherboard, making this option incorrect.
C) Expansion bus
The expansion bus serves as a communication pathway for data transfer between various components. While it is crucial for connecting removable hardware, it does not itself contain soldered parts or slots, rendering this option incorrect.
D) Motherboard
The motherboard is the main circuit board housing soldered components and providing slots for additional hardware. It is designed to connect various parts of the computer, including removable components, making it the correct choice.
Conclusion
The motherboard is definitively the correct answer as it contains both soldered components and slots for removable hardware, fulfilling the criteria outlined in the question. In contrast, the other options either do not involve removable hardware or lack the required features, confirming their incorrectness.
