D316 IT Foundations - Set 4 - Part 2

Correct Answer: Control I/O devices

The Southbridge controls slower input/output devices such as USB ports, audio, and storage controllers.

Correct Answer: Render images for display

The GPU (Graphics Processing Unit) handles rendering graphics and images for display on monitors.

Correct Answer: PCIe

PCIe (Peripheral Component Interconnect Express) is the most common interface for modern high-speed devices like graphics cards.

Correct Answer: RAID 1

RAID 1 mirrors data across two drives, providing redundancy in case one drive fails.

Correct Answer: Hybrid drive

Hybrid drives combine SSD technology with traditional HDDs, offering faster access to frequently used data.

Correct Answer: SSH

SSH (Secure Shell) is a cryptographic protocol used for secure remote access to computers over a network.

Correct Answer: Overclocking

Overclocking involves increasing the CPU's clock speed beyond the manufacturer's specifications for improved performance.

Correct Answer: SATA

SATA (Serial ATa) connectors are commonly used for connecting internal hard drives and SSDs in modern desktops.

Correct Answer: Virtualization

Virtualization allows multiple virtual machines (VMs) to run on a single physical server, optimizing resource utilization.

Correct Answer: Cool components

A heatsink dissipates heat from components such as the CPU to prevent overheating and maintain optimal performance.

Correct Answer: HDD

HDDs (Hard Disk Drives) are commonly used for backups due to their large storage capacity and cost-effectiveness.

Correct Answer: SSD

SSDs are more vulnerable to ESD because they contain sensitive electronic components compared to traditional mechanical HDDs.

Correct Answer: 5 Gbps

USB 3.0 supports a maximum transfer rate of up to 5 Gbps, offering significantly faster speeds than USB 2.0.

Correct Answer: Detect and correct memory errors

ECC (Error Correcting Code) memory detects and corrects single-bit errors in server memory to ensure data integrity.

Correct Answer: USB

USB (Universal Serial Bus) is the most common interface for connecting external storage devices like flash drives and external hard drives.

Correct Answer: ROM

ROM (Read-Only Memory) is non-volatile and retains its contents even when the system is powered off.

Correct Answer: Connect cables

A patch panel is used in networking to organize and connect various network cables for efficient routing.

Correct Answer: Water cooling

Water cooling is commonly used in high-performance systems like gaming PCs to efficiently dissipate heat from the CPU and GPU.

Correct Answer: Power Supply Unit (PSU)

The PSU converts AC power from the wall into low-voltage DC power used by computer components.

Correct Answer: Direct data between devices

A network switch is responsible for directing and managing the flow of data between devices in a LAN.
