Explain why regular cleaning of computer hardware is important for maintaining its functionality. Use evidence from basthe images to support your answer.
Dust buildup can block cooling systems, leading to overheating and potential hardware failure.
Dust makes computers look unattractive but does not affect performance.
Dust only affects the external appearance of computers.
Dust improves the efficiency of cooling fans.
At what temperature range does a good cooler keep the CPU?
90-110°F
50-70°F
120-150°F
60-80°F
Why is it important for a CPU cooler to maintain the temperature within the recommended range?
To prevent overheating and ensure optimal performance and longevity of the CPU
To make the computer look more attractive
To reduce the amount of electricity used
To allow the computer to run more games
Why should you avoid stacking thermal pads when assembling a computer cooling system?
Stacking thermal pads can reduce heat transfer efficiency.
Stacking thermal pads increases processor speed.
Stacking thermal pads improves electrical insulation.
Stacking thermal pads is required for all CPUs.
Which component can be added to a computer to help keep it cool?
Extra fans
More hard drives
Additional USB ports
Extra speakers
Why do bigger fans work better than small ones in a computer case?
They move more air and cool more efficiently
They use less electricity
They are easier to install
They make less noise
Explain how adding extra fans to a computer case can impact the overall performance and longevity of the system.
Extra fans help dissipate heat, preventing overheating, which can improve performance and extend the lifespan of components.
Extra fans increase the weight of the computer, making it harder to move.
Extra fans use more electricity, which can slow down the computer.
Extra fans make the computer louder, which can distract users.
Why is it important to check fan size and case compatibility before installing a new PC fan?
To ensure the fan matches the color of the case
To make sure the fan fits and can be mounted properly
To increase the speed of the computer
To reduce the cost of the fan
A student wants to upgrade their PC cooling system. What should they do before purchasing new fans?
Buy the largest fan available
Measure available mounting points or read the manual
Choose fans based on color preference
Ignore compatibility and install any fan
When building a new computer system, what is one option regarding the power supply?
Buy a computer case that already has a power supply.
Use the old power supply from a previous system.
Ignore the need for a power supply.
Build a system without a case.
Why might a power supply not be suitable for a computer system, requiring replacement?
The power supply isn't strong enough for the system.
The power supply is too expensive.
The power supply is too small in size.
The power supply is too noisy.
A user is building a high-performance computer system. What strategic consideration should they make regarding the power supply?
Ensure the power supply is strong enough for the system's requirements.
Choose the cheapest power supply available.
Select a power supply based only on its color.
Ignore the power supply specifications.
What is the maximum power output rating of the Cooler Master RS-650-AMAA-B1 power supply?
650W
500W
750W
400W
What is the first step in determining how much power (wattage) your computer needs?
Check the manufacturer's website
Add up the power used by all parts inside the computer and USB devices
Buy the largest power supply available
Only consider the CPU wattage
What is the maximum data transfer speed of a USB 3.1 Type A port?

Which port would you use to connect to a wired local area network (LAN)?
RJ-45
HDMI
USB Type C
WiFi Antenna
Compare the data transfer speeds of USB 2.0 Type A and USB 3.0 Type A ports. Which one is faster and by how much?
USB 3.0 Type A is faster by 4.52Gb/s
USB 2.0 Type A is faster by 4.52Gb/s
Both have the same speed
USB 2.0 Type A is faster by 5Gb/s
Explain why WiFi antennas are included on the back panel of a computer motherboard. What is their function?
To enable wireless network connectivity
To improve audio quality
To connect external monitors
To provide power to the motherboard
What is the name of the USB connector type that is commonly used for high-speed data transfer and is labeled with "SSC" in the image?
USB-B Micro Superspeed
USB-A
USB4
Thunderbolt 3 & 4
Compare USB-C and USB-A connectors in terms of their physical design and discuss one advantage of USB-C over USB-A.
USB-C is reversible and smaller, making it easier to plug in; USB-A is larger and not reversible.
USB-A is reversible and smaller, making it easier to plug in; USB-C is larger and not reversible.
Both USB-A and USB-C are the same size and shape.
USB-A supports higher data transfer speeds than USB-C.
