PC Hardware MCQ - Unique Foundation

Welcome to your Hardware Test1

1.

What is a potential downside of using a SMPS compared to a linear power supply?

SMPS can introduce high-frequency switching noise into the power supply.

SMPS are less reliable.

SMPS are generally more expensive.

2.

SMPS are generally considered more efficient than linear power supplies because:

They generate less heat.

They convert all the input power to usable DC power.

They operate at a higher voltage.

3.

What is the typical operating principle of an SMPS?

It uses a transformer to step down the AC voltage and then rectifies it to DC.

It switches the AC voltage on and off rapidly, controlling the average voltage output.

It stores energy in a capacitor to provide a constant DC voltage.

4.

Which of the following components is NOT directly mounted on the motherboard?

RAM

Hard Disk Drive (HDD)

Southbridge

5.

Which of the following components is NOT typically found in a SMPS?

Resistor

Transformer

Rectifier

6.

Expansion slots on the motherboard allow users to install additional components like:

The power supply unit

RAM sticks

The CPU (Central Processing Unit)

7.

The chipset on a motherboard plays a crucial role in:

Facilitating communication between the CPU, RAM, and other devices

Storing data permanently

Providing power to all components

8.

What is the main function of a Switch Mode Power Supply (SMPS) in a computer?

To filter out noise and interference from the power supply.

To convert AC current from the wall outlet to DC current.

To regulate the voltage from the wall outlet to a constant DC voltage suitable for computer components.

9.

What is the primary function of the BIOS/UEFI on the motherboard?

Processing data and calculations

Providing the initial instructions for booting the computer

Running applications and software

10.

The motherboard is often referred to as the

Central Processing Unit (CPU)

Random Access Memory (RAM)

Main circuit board
