PC Hardware MCQ - Unique Foundation

Welcome to your Hardware Test1

1.

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

Hard Disk Drive (HDD)

Southbridge

RAM

2.

The chipset on a motherboard plays a crucial role in:

Storing data permanently

Facilitating communication between the CPU, RAM, and other devices

Providing power to all components

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 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.

4.

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

Resistor

Rectifier

Transformer

5.

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.

6.

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.

7.

The motherboard is often referred to as the

Random Access Memory (RAM)

Main circuit board

Central Processing Unit (CPU)

8.

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

Processing data and calculations

Running applications and software

Providing the initial instructions for booting the computer

9.

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

The CPU (Central Processing Unit)

RAM sticks

The power supply unit

10.

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

SMPS are less reliable.

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

SMPS are generally more expensive.
