Question 1

Which type of storage interface offers the fastest data transfer speeds for modern SSDs?

Accepted Answer

NVMe (PCIe)

Answer

NVMe drives use the PCIe bus and can reach sequential read speeds over 7,000 MB/s, far exceeding SATA III's 600 MB/s ceiling.

Question 2

What does the term 'TDP' refer to in the context of CPUs and GPUs?

Accepted Answer

Thermal Design Power

Answer

TDP (Thermal Design Power) is the maximum amount of heat a cooling solution must dissipate to keep the component running within safe temperatures.

Question 3

A user connects an external monitor but gets no signal. Which component is MOST likely responsible if the integrated GPU works fine?

Accepted Answer

Dedicated GPU

Answer

If the integrated GPU outputs video but the discrete GPU does not, the dedicated GPU (or its driver/power connectors) is the likely failure point.

Question 4

Which peripheral interface standard supports both data transfer and video output through the same connector?

Accepted Answer

Thunderbolt 4

Answer

Thunderbolt 4 uses the USB-C connector and can simultaneously carry PCIe data, DisplayPort video, and up to 100W of power.

Question 5

What is the primary function of a heat sink in a computer system?

Accepted Answer

Dissipate heat away from the CPU

Answer

A heat sink uses metal fins and conduction to transfer heat from a processor to the surrounding air, preventing thermal throttling.
