Hardware Test1 - Unique Foundation

Welcome to your Hardware Test1

1.

The motherboard is often referred to as the

Main circuit board

Central Processing Unit (CPU)

Random Access Memory (RAM)

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

Providing the initial instructions for booting the computer

Running applications and software

Processing data and calculations

4.

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 stores energy in a capacitor to provide a constant DC voltage.

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

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 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.

6.

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.

7.

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

RAM

Southbridge

Hard Disk Drive (HDD)

8.

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

9.

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

Transformer

Resistor

Rectifier

10.

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

The CPU (Central Processing Unit)

RAM sticks

The power supply unit
