Question 1

What is the purpose of ECC RAM in a server environment?

Accepted Answer

Detect and correct single-bit memory errors

Answer

ECC (Error-Correcting Code) RAM uses extra bits to automatically detect and correct single-bit errors, preventing data corruption in critical workloads.

Question 2

Which port type was specifically designed to connect digital cameras and camcorders to a PC using a 4- or 6-pin connector?

Accepted Answer

FireWire (IEEE 1394)

Answer

FireWire (IEEE 1394) was popular for DV camcorder transfer due to its isochronous data delivery, which guarantees consistent bandwidth for video streams.

Question 3

A laptop suddenly throttles performance when running on battery. What hardware feature causes this behavior?

Accepted Answer

CPU power management / TDP limits

Answer

To conserve battery life, the CPU's power management reduces clock speed and voltage when the system is unplugged, limiting performance.

Question 4

What does 'PCIe x16' indicate about an expansion slot?

Accepted Answer

It has 16 PCIe lanes for high-bandwidth transfer

Answer

The 'x16' designation means the slot uses 16 PCIe lanes, providing maximum bandwidth—most dedicated GPUs require an x16 slot.

Question 5

Which type of display technology uses organic compounds that emit light without a backlight?

Accepted Answer

OLED

Answer

OLED panels use organic electroluminescent compounds where each pixel generates its own light, enabling true blacks and high contrast ratios.
