Transformer
Rectifier
Regulator
Fan
Koffi is building a new gaming PC and is considering different power supply units (PSUs). What is an advantage of a modular PSU over a non-modular PSU?
Higher power output.
Improved compatibility with older motherboards.
Detachable cables reduce clutter and improve airflow.
Redundant failover support.
How does dust buildup impact the cooling system in Kelina's computer?
Increases airflow.
Reduces cooling efficiency.
Improves fan performance.
Prevents air gaps in thermal paste.
What precaution should Koffi take before moving a PC with an open-loop liquid cooling system?
Clean the water blocks.
Drain the coolant.
Remove the pump.
Disconnect the radiator fans.
Kelina is trying to connect her external hard drive to her laptop for extra storage. Which connection type is most commonly used to connect external storage devices?
HDMI
USB
eSATA
PCIe
Luis and Maura are discussing the technology behind SSDs. Luis mentions that wear leveling is an important feature in these devices. Maura asks, 'Why is wear leveling used in SSDs?'
To reduce energy consumption.
To optimize read performance.
To evenly distribute write operations.
To improve cooling efficiency.
During a science project, Robbie and Xavier were discussing how the speed of a hard disk drive (HDD) affects its performance. Robbie mentioned that one specific feature determines the speed at which the platters spin. What is that feature?
Internal transfer rate
Rotational latency
Revolutions per minute (RPM)
Access time
During a group project, Kelina and Oscar are discussing how to ensure their data is safe and accessible. They consider different storage solutions and realize that implementing RAID could be beneficial. What is the primary purpose of implementing RAID?
To improve CPU performance.
To provide fault tolerance and redundancy.
To replace SSDs with HDDs.
To reduce power consumption.
Emma and Tornita are working on a project that uses a RAID 0 configuration to store their data across multiple disks. One day, one of the disks fails. What happens to their data?
The data on the other disks remains intact.
The RAID volume fails completely.
The system uses parity to rebuild the lost data.
The other disk takes over seamlessly.
Koffi and Brad are setting up a new server for their project and want to ensure data redundancy. They decide to configure RAID 10 for better performance and fault tolerance. How many disks are required at minimum to configure RAID 10?

Luis and Kelina are discussing different types of storage devices for their upcoming project. They want to know which of the following is not a removable storage medium.
USB flash drive
External HDD
SD card
RAID 10 array
In a computer lab, Xavier is trying to run multiple applications at once, but his computer starts to slow down. He wonders what the primary purpose of virtual memory is in helping his system manage these applications efficiently.
To improve CPU speed.
To protect physical RAM from damage.
To extend system RAM using disk storage.
To replace physical RAM entirely.
In a computer lab, Emma is trying to understand how the memory controller works in system RAM. She learns that it plays a crucial role in managing the communication between the CPU and RAM. What is the specific function of the memory controller?
It connects the CPU to virtual memory.
It moves instructions between RAM and the CPU.
It synchronizes RAM with the system clock.
It controls the size of the swap file.
While working on upgrading their laptops, Xavier and Emma were discussing the different types of memory modules. Xavier asked, 'Which memory module form factor is typically used in laptops?'
DIMM
SODIMM
SIMM
RIMM
What happens if Angel and Oscar install RAM modules of different speeds in a dual-channel system?
The system will use the speed of the slowest module.
The system will refuse to boot.
The system will operate at the highest supported speed.
Dual-channel mode will still run at full speed.
During a computer science class, Luis and Tornita were discussing the importance of different types of RAM. Tornita mentioned that ECC RAM has a specific function that helps maintain data integrity. What is the primary function of ECC RAM?
Increase memory speed.
Detect and correct single-bit memory errors.
Improve power efficiency.
Reduce the system's electrical load.
While discussing the latest mobile devices in class, Paul asked his friends which type of CPU architecture is most commonly used in these gadgets. What do you think they answered?
x86
x64
ARM
CISC
While working on a computer build, Oscar was trying to install a CPU into a ZIF (Zero Insertion Force) socket. What feature does this socket provide when installing the CPU?
Reduces the need for thermal grease.
Requires no pressure to insert the CPU.
Aligns the CPU with the motherboard slots automatically.
Prevents electrostatic discharge.
