D316 IT Foundations - Set 3 - Part 2

Correct Answer: VRM

Voltage Regulator Modules (VRMs) ensure the CPU receives the correct voltage for stable operation.

Correct Answer: ROM

ROM retains data even when the computer is powered off, making it non-volatile.

Correct Answer: Compatibility issues with certain components

Aftermarket PSUs may not always be compatible with all system components or offer the required power.

Correct Answer: Parity

RAID 5 uses parity data, which allows for fault tolerance by reconstructing lost data if a single drive fails.

Correct Answer: ITX

ITX is the smallest form factor among the listed options, often used for compact systems.

Correct Answer: Store frequently accessed data for quick retrieval

Cache memory stores frequently accessed data to reduce the time the CPU spends retrieving data from main memory.

Correct Answer: Video output and data transfer

Thunderbolt ports are versatile, supporting both high-speed data transfer and video output.

Correct Answer: Universal Serial Bus

USB (Universal Serial Bus) is a standard for data transfer and connection between devices.

Correct Answer: HDMI

HDMI is a widely used video connector for transmitting high-definition video and audio.

Correct Answer: Convert AC power to DC power

A PSU converts alternating current (Ac) from a wall outlet into direct current (Dc) for the computers components.

Correct Answer: Modem or telephone connections

RJ11 connectors are commonly used for telephone and dial-up modem connections.

Correct Answer: RAID 0

RAID 0, also known as disk striping, splits data across multiple disks to increase performance but does not provide any redundancy. If one disk fails, all data is lost.

Correct Answer: SRAM

SRAM (Static RAM) is faster than DRAM and is typically used for CPU cache because of its speed and efficiency.

Correct Answer: Store data persistently

Solid-State Drives (SSDs) store data persistently using flash memory, making them faster than traditional HDDs.

Correct Answer: HDMI

HDMI is the standard video output port for high-definition displays on modern computers.

Correct Answer: Improved airflow and cable management

Modular power supplies allow users to connect only the cables they need, reducing clutter and improving airflow inside the case.

Correct Answer: Devices that can be connected or removed without shutting down the system

Hot-swappable devices can be added or removed from a running system without requiring a reboot.

Correct Answer: Control communication between the CPU and high-speed components like RAM and GPUs

The northbridge manages communication between the CPU and faster components like RAM, GPUs, and PCIe devices.

Correct Answer: RAID 5

RAID 5 requires at least three disks and uses parity to provide redundancy while improving read performance through striping.

Correct Answer: Distribute heat away from components

Thermal pads help dissipate heat from components like CPUs and GPUs by improving thermal conductivity between the component and the heat sink.
