What is the primary function of a power supply in a computer system?

• To store data

• To convert AC power to DC power

• To increase internet speed

• To cool down the CPU

Which type of current is used inside a computer?

• Alternating Current (AC)

• Direct Current (DC)

• Static Current

• Pulsating Current

Why is DC power preferred for computer components over AC power?

• DC power is cheaper to produce

• DC power is more predictable and reliable

• DC power is more environmentally friendly

• DC power is faster to transmit

What are the standard DC voltage outputs provided by an ATX power supply?

• +3.3 volts, +/- 5 volts, and +/- 12 volts

• +5 volts, +/- 10 volts, and +/- 15 volts

• +1.5 volts, +/- 3 volts, and +/- 6 volts

• +2 volts, +/- 4 volts, and +/- 8 volts

Explain why it is important to avoid overloading one circuit in a power supply.

• It can cause the computer to run faster

• It can lead to overheating and potential damage

• It can improve the graphics performance

• It can increase the storage capacity

How does the concept of a "rail" in a power supply help in distributing power?

• It allows for faster data transfer

• It helps in organizing cables

• It distributes power to multiple devices without overloading

• It increases the lifespan of the power supply

What might happen if a computer component receives incorrect levels of DC voltage?

• The component may function more efficiently

• The component may become damaged or fail

• The component may increase its processing speed

• The component may reduce its power consumption

Why do most modern components require a +12 volt output from the power supply?

• It is the most energy-efficient voltage

• It provides the necessary power for high-performance components

• It is the only voltage that can be converted to AC

• It is the safest voltage for all components

Describe the difference between AC and DC power in terms of current flow.

• AC power flows in one direction, while DC power alternates direction

• AC power alternates direction, while DC power flows in one direction

• Both AC and DC power flow in one direction

• Both AC and DC power alternate direction

What is the role of negative particles in DC power?

• They create a bidirectional current flow

• They are drawn toward a positive charge, creating a unidirectional flow

• They increase the voltage level

• They decrease the current flow
