ITM 200 Information Technology Hardware Essentials Quiz

Video ports are specific ports on a computer or device that allow connectivity to external displays or monitors. The correct answer includes commonly used video ports, while the incorrect answers are not typically used for video output.

The correct answer is SUPERSPEED because it refers to USB 3.0 ports that have faster data transfer rates than Hi-Speed USB ports (USB 2.0). Hi-Speed USB ports have a maximum transfer rate of 480 Mbps whereas SuperSpeed USB ports can achieve up to 5 Gbps.

S/PDIF ports are specifically designed for transmitting high quality digital audio signals.

Expansion slots on a motherboard are primarily used to add more ports for connectivity, such as additional USB, Ethernet, or audio ports. They do not directly affect the speed, graphics performance, or power consumption of the motherboard.

In the United States, the standard voltage for residential outlets is 120 volts. Therefore, the correct setting for a dual-voltage selector switch on a power supply when using a computer in the United States is 115 volts.

The best way to determine if a cable is for data and instruction or power is by tracing it from the source to the destination. This ensures you know what the cable is used for based on where it is connected.

SATA (SERIAL ATA) is the commonly used technology standard for hard drives to interface with the motherboard in modern systems, offering high speed and compatibility. IDE, SCSI, and NVMe are also storage interfaces, but SATA is the most prevalent in today's computers.

The original ATX motherboard used a 20-PIN power connector for the P1 connector. This standard has since evolved to include more pins for newer motherboards.

PCIe (express) expansion slots require extra power beyond what the older 20-pin P1 power connector on the motherboard can provide, leading to the addition of 4 more pins to the power connector.

A video card often requires additional power to function properly, especially higher-end models that demand more power for optimal performance. The 12V 6-pin power connector is commonly used to provide this extra power. It can usually be found on the video card itself, as well as on the power supply unit of the computer.

The 4-pin auxiliary connector on a motherboard is specifically designed to provide additional power to the system components.

The 4-pin Molex connector is specifically designed to provide power to older IDE drives, such as hard disk drives and optical drives. It is not used for USB devices, external hard drives, or newer types of storage devices.

Laptops are typically more expensive than desktop computers due to their smaller and more portable nature, which often requires specialized and compact components. This added cost is reflected in the overall price of laptops compared to desktops with similar power and features.

Express Card slots are designed to be compatible with PCI and PCIe (express) buses, allowing for high-speed data transfer and connectivity.

A docking station is typically connected to a laptop using a specific DOCKING PORT designed for that purpose.

In desktop computers, DIMM (Dual In-line Memory Module) memory modules are commonly used, while in laptops, SODIMM (Small Outline Dual In-line Memory Module) modules are more prevalent due to their smaller form factor.

ESD strap helps in grounding the technician and preventing static discharge, while screwdriver, hammer, and pliers can cause ESD damage by transferring static electricity to components.

A POST diagnostic card is used to report errors that occur during the Power-On Self Test (POST) process of a computer system.

The BIOS primarily deals with basic system functions such as checking RAM, handling video output, and managing audio. It is not directly responsible for handling storage, managing networking, or optimizing CPU usage.

Stacking boards on top of each other can lead to dislodging of chips, which can result in malfunctioning or non-functional components.

When assembling a desktop computer, it is important to start by installing the motherboard first as it serves as the foundation for all other components to be connected to.

The correct answer is 'PREVENT SHORT'. Raised screw holes or standoffs prevent the motherboard from coming into contact with the metal of the desktop case, thereby preventing a short circuit.

When the pins on the motherboard front panel header are not labeled, the best course of action is to refer to the user-guide for the motherboard. It will provide the necessary information on which pins to use for each wire, ensuring proper installation.

Laptops are usually more expensive than desktop computers with comparable power and features due to their smaller size, portability, and convenience. These factors contribute to the higher cost of laptops compared to desktops.

The service manual provides detailed directions and steps for reassembly, which helps save time and ensures the laptop is put back together correctly.

When a laptop internal device fails, the correct options to deal with the problem are following the service manual, returning with warranty, and obtaining replacement parts. Ignoring the issue or physically damaging the laptop are not viable solutions, and relying on a miracle is not a practical approach to fixing technical problems.

When servicing internal laptop components, it is essential to disconnect the battery to prevent any electrical mishaps or damage to the components.
