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

    Answer: No moving mechanical parts

    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.

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

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

    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.

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

    Answer: The travel distance at which the keystroke is registered

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

  4. What does 'DPI' measure on a computer mouse?

    Answer: Dots per inch — sensor sensitivity to physical movement

    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.

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

    Answer: Replace the motherboard or capacitor

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

  6. Which standard governs the physical dimensions and mounting hole positions of ATX motherboards?

    Answer: ATX form factor specification

    The ATX form factor specification defines the board's dimensions (305×244 mm), mounting holes, and rear I/O panel position for compatibility with ATX cases.

  7. What is 'overclocking' in the context of computer hardware?

    Answer: Running a component at a higher frequency than its manufacturer's default rating

    Overclocking manually increases a component's clock speed beyond factory specifications to gain performance, usually at the cost of higher heat and power consumption.
