PC Hardware MCQ - Unique Foundation

Welcome to your Hardware Test1

1.

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

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 typically found in a SMPS?

Resistor

Rectifier

Transformer

4.

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.

5.

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.

6.

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

7.

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

Hard Disk Drive (HDD)

RAM

Southbridge

8.

The motherboard is often referred to as the

Random Access Memory (RAM)

Main circuit board

Central Processing Unit (CPU)

9.

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.

10.

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

The CPU (Central Processing Unit)

The power supply unit

RAM sticks
