Question 1

What is the main advantage of a solid-state drive (SSD) over a traditional hard disk drive (HDD) in terms of physical design?

Accepted Answer

No moving mechanical parts

Answer

SSDs store data on NAND flash chips with no spinning platters or read/write heads, making them faster, quieter, and more shock-resistant than HDDs.

Question 2

Which specification defines the maximum resolution and refresh rate a DisplayPort cable can support?

Accepted Answer

The DisplayPort version (e.g., 1.4, 2.1)

Answer

Each DisplayPort version specifies a maximum bandwidth; for example, DP 1.4 supports 8K at 60 Hz or 4K at 120 Hz with DSC compression.

Question 3

In a mechanical keyboard, what is the role of the switch's 'actuation point'?

Accepted Answer

The travel distance at which the keystroke is registered

Answer

The actuation point is the specific travel depth at which the switch closes the circuit and sends a keystroke signal to the computer.

Question 4

What does 'DPI' measure on a computer mouse?

Accepted Answer

Dots per inch — sensor sensitivity to physical movement

Answer

DPI (dots per inch) describes how many pixels the cursor moves on screen for every inch the mouse moves physically; higher DPI means faster cursor movement.

Question 5

A technician finds a capacitor on a motherboard that is bulging at the top. What should they do?

Accepted Answer

Replace the motherboard or capacitor

Answer

A bulging capacitor indicates it has failed and can cause system instability or fire; the motherboard or the capacitor itself must be replaced.
