PC Hardware MCQ - Unique Foundation

Welcome to your Hardware Test1

1.

The chipset on a motherboard plays a crucial role in:

Providing power to all components

Facilitating communication between the CPU, RAM, and other devices

Storing data permanently

2.

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

Providing the initial instructions for booting the computer

Processing data and calculations

Running applications and software

3.

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

Southbridge

Hard Disk Drive (HDD)

RAM

4.

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

SMPS are generally more expensive.

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

SMPS are less reliable.

5.

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

They convert all the input power to usable DC power.

They generate less heat.

They operate at a higher voltage.

6.

The motherboard is often referred to as the

Central Processing Unit (CPU)

Random Access Memory (RAM)

Main circuit board

7.

What is the typical operating principle of an SMPS?

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

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

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

8.

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

The CPU (Central Processing Unit)

RAM sticks

The power supply unit

9.

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

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.

To filter out noise and interference from the power supply.

10.

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

Transformer

Rectifier

Resistor
