PC Hardware MCQ - Unique Foundation

Welcome to your Hardware Test1

1.

What is the typical operating principle of an SMPS?

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.

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

2.

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

The CPU (Central Processing Unit)

RAM sticks

The power supply unit

3.

The motherboard is often referred to as the

Random Access Memory (RAM)

Main circuit board

Central Processing Unit (CPU)

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.

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

Southbridge

RAM

Hard Disk Drive (HDD)

6.

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

7.

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

Transformer

Rectifier

Resistor

8.

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 generally more expensive.

SMPS are less reliable.

9.

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 convert AC current from the wall outlet to DC current.

To regulate the voltage from the wall outlet to a constant DC voltage suitable for computer components.

10.

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

They operate at a higher voltage.

They generate less heat.

They convert all the input power to usable DC power.
