PC Hardware MCQ - Unique Foundation

Welcome to your Hardware Test1

1.

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

RAM sticks

The CPU (Central Processing Unit)

The power supply unit

2.

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

Southbridge

RAM

Hard Disk Drive (HDD)

3.

The motherboard is often referred to as the

Random Access Memory (RAM)

Main circuit board

Central Processing Unit (CPU)

4.

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

Providing the initial instructions for booting the computer

Processing data and calculations

Running applications and software

5.

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.

6.

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

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.

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

Transformer

Rectifier

Resistor

9.

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

To filter out noise and interference from the power supply.

10.

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.
