Question 21

The hardware component that contains soldered parts and slots for other pieces of hardware that can be removed is the motherboard.

The motherboard serves as the main printed circuit board in a computer, featuring both soldered components, such as the CPU and RAM slots, and various expansion slots for additional hardware like graphics cards and sound cards.

A) Motherboard

The motherboard is the primary component that indeed contains soldered parts and slots for removable hardware. It hosts essential components like the CPU and RAM, while also providing slots for expansion cards, making it the correct answer to the question.

B) Hard drive

The hard drive is a storage device that does not contain soldered parts or multiple slots for expansion. It serves to store data and does not function as a hub for other components, thus making it an incorrect option.

C) System clock

The system clock is a timing device that regulates the operation of the computer but does not have any slots or soldered parts for additional hardware. Its function is limited to timing and synchronization, hence it is not the correct answer.

D) Expansion bus

The expansion bus is a communication system that transfers data between the CPU and other components. While it plays a role in connecting hardware, it does not itself contain soldered parts or slots for removable hardware, making this option incorrect.

Conclusion

The motherboard is the only component among the options that fits the description of containing both soldered parts and slots for removable hardware, which is crucial for system expandability. All other options, while important in their functions, do not fulfill the criteria outlined in the question.
