PC Hardware MCQ - Unique Foundation

Welcome to your Hardware Test1

1.

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

Resistor

Rectifier

Transformer

2.

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

They operate at a higher voltage.

They convert all the input power to usable DC power.

They generate less heat.

3.

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

SMPS are less reliable.

SMPS are generally more expensive.

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

4.

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

5.

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

6.

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

The power supply unit

The CPU (Central Processing Unit)

RAM sticks

7.

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.

8.

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.

9.

The motherboard is often referred to as the

Central Processing Unit (CPU)

Main circuit board

Random Access Memory (RAM)

10.

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

RAM

Southbridge

Hard Disk Drive (HDD)
