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 are generally more expensive.

SMPS are less reliable.

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

2.

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

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

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 typically found in a SMPS?

Resistor

Transformer

Rectifier

5.

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

Running applications and software

Processing data and calculations

Providing the initial instructions for booting the computer

6.

The motherboard is often referred to as the

Central Processing Unit (CPU)

Main circuit board

Random Access Memory (RAM)

7.

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

RAM

Southbridge

Hard Disk Drive (HDD)

8.

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

They convert all the input power to usable DC power.

They operate at a higher voltage.

They generate less heat.

9.

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

10.

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

RAM sticks

The CPU (Central Processing Unit)

The power supply unit
