Welcome to your Hardware Test1

1.

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

Transformer

Resistor

Rectifier

2.

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.

3.

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

Southbridge

RAM

Hard Disk Drive (HDD)

4.

The motherboard is often referred to as the

Main circuit board

Central Processing Unit (CPU)

Random Access Memory (RAM)

5.

What is the typical operating principle of an SMPS?

It switches the AC voltage on and off rapidly, controlling the average voltage output.

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.

6.

The chipset on a motherboard plays a crucial role in:

Providing power to all components

Storing data permanently

Facilitating communication between the CPU, RAM, and other devices

7.

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

RAM sticks

The power supply unit

The CPU (Central Processing Unit)

8.

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.

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.

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

Running applications and software

Providing the initial instructions for booting the computer

Processing data and calculations
