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.

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.

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

RAM

Hard Disk Drive (HDD)

Southbridge

4.

The motherboard is often referred to as the

Central Processing Unit (CPU)

Random Access Memory (RAM)

Main circuit board

5.

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.

6.

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

Resistor

Rectifier

Transformer

7.

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 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.

8.

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

RAM sticks

The power supply unit

The CPU (Central Processing Unit)

9.

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.

10.

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
