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)

RAM

Southbridge

2.

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

Transformer

Rectifier

Resistor

3.

The motherboard is often referred to as the

Central Processing Unit (CPU)

Main circuit board

Random Access Memory (RAM)

4.

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

5.

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

Providing the initial instructions for booting the computer

Running applications and software

Processing data and calculations

6.

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.

7.

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

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

SMPS are less reliable.

SMPS are generally more expensive.

8.

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

The power supply unit

RAM sticks

The CPU (Central Processing Unit)

9.

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.

10.

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.
