Welcome to your Hardware Test1

1.

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.

2.

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

Transformer

Resistor

Rectifier

3.

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

They convert all the input power to usable DC power.

They generate less heat.

They operate at a higher voltage.

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 main function of a Switch Mode Power Supply (SMPS) in a computer?

To convert AC current from the wall outlet to DC current.

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.

6.

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

7.

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.

8.

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

Southbridge

RAM

Hard Disk Drive (HDD)

9.

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

RAM sticks

The power supply unit

The CPU (Central Processing Unit)

10.

The motherboard is often referred to as the

Random Access Memory (RAM)

Central Processing Unit (CPU)

Main circuit board
