IT Essentials Chapter 2 Exam

Deven, Sam, and Aiden are working on a school project where they need to open a computer case to upgrade their gaming PC. What is a good safety precaution they should take?

• Place tape over the case edges that are sharp.

• Remove the cover (or door) of the computer case before installing or removing parts.

• Remove the connections to the front panel before extending the case fully open.

• Ensure that any loose clothing such as a tie or shirt stay in constant contact with the case when handling internal components.

Answer explanation

A good safety precaution when opening a computer case is to remove the cover or door before installing or removing parts. This ensures that you have clear access to the internal components and reduces the risk of damaging any parts or causing injury to yourself while working inside the case.

Deven and Sam are setting up a gaming computer for their friend Aiden. They realized that they need to replace the power supply. Which two factors should Deven and Sam consider when obtaining the replacement part? (Choose two.)

• type of case

• input voltage level of 12 or 5 VDC

• number of internal fans

• output voltage

• wattage

Answer explanation

When replacing a power supply, the technician should consider the wattage and output voltage. Wattage ensures the power supply can handle the system's power requirements, while output voltage ensures compatibility with the components. The type of case, input voltage level, and number of internal fans are not as crucial for obtaining the correct replacement part.

Sam, Aiden, and Deven are building a gaming PC together. They are discussing which component will have the most influence when selecting the case and power supply. What do you think they concluded?

• video card

• sound card

• RAM module

• motherboard

Answer explanation

The motherboard has the most influence when selecting the case and power supply for a new PC. This is because the motherboard determines the size and form factor of the case, as well as the power requirements for the system. The other components, such as video card, sound card, and RAM module, are secondary considerations.

Deven, Aiden, and Sam are building a custom gaming PC for their computer science project. They need to install a RAM module on the motherboard. In which slot should they install it?

• slot A

• slot B

• slot C

• slot D

Answer explanation

A memory module is installed in the section B of the motherboard. This section is specifically designed to accommodate memory modules, ensuring proper connection and functionality. The other sections are not suitable for memory module installation.

Deven, Sam, and Aiden are working on a computer hardware project for their school. They found a device in their computer lab but are unsure about its type. Can you help them identify the device?

• It's a media reader

• It's an optical drive

• It's a hard disk drive

• It's a SATA drive

Answer explanation

As the question does not provide an image or description of the device, it is impossible to determine which device is shown. The options provided are media reader, optical drive, hard disk drive, and SATA drive, but without further context, we cannot identify the correct choice.

Deven and Sam are working on a school project to build a custom computer. They need to install a graphics card and notice an expansion slot on the motherboard. Aiden, their computer science teacher, asks them, 'Which type of expansion slot are you looking at?'

• AGP

• PCI

• PCIe x16

• KVM switch

Answer explanation

The question asks about the type of expansion slot shown. The correct answer is AGP. AGP, or Accelerated Graphics Port, is a high-speed point-to-point channel for attaching a video card to a computer's motherboard. It is different from other options like PCI and PCIe x16, which are types of connection interfaces, and KVM switch, which is a hardware device.

Sam, Deven, and Aiden are working together to build a custom gaming PC. They need to connect the CPU to RAM and other components on the motherboard. Which PC motherboard bus should they use for this purpose?

• front-side

• back-side

• system

• expansion

Answer explanation

The front-side bus (FSB) is the bus that connects the CPU to the main memory (RAM) and other components on the motherboard. This is why the correct answer to the question, 'Which PC motherboard bus is used to connect the CPU to RAM and other motherboard components?' is 'front-side'.

Aiden, Sam, and Deven are planning to enhance their gaming experience by installing a new high-performance graphics card into their gaming PC. What components might they need to ensure the graphics card functions properly?

• PCI expansion slot

• PCIe x 8 expansion slot

• Two 8-pin power connectors

• 24-pin ATX power connector

Answer explanation

The question asks about the requirements for operating a high-end video adapter card. Among the given options, 'Two 8-pin power connectors' is the correct choice. High-end video adapter cards often require additional power, which is provided by the two 8-pin power connectors. Other options like PCI expansion slot, PCIe x 8 expansion slot, and 24-pin ATX power connector are not specifically required for the operation of a high-end video adapter card.

Aiden, Sam, and Deven are setting up a new server for their startup's data center. In which type of computer system is buffered memory commonly used?

• gaming laptops

• gaming computers

• business PCs

• servers

• tablets

Answer explanation

Buffered memory is commonly used in servers. This is because servers often handle large amounts of data and require a buffer to manage the data flow efficiently. Buffered memory helps to reduce the load on the server's processor, allowing it to perform better. Other options like gaming laptops, gaming computers, business PCs, and tablets typically do not use buffered memory.

Aiden, Sam, and Deven are working together on a school project to build a custom computer. They are puzzled about the purpose of an I/O connector plate. Can you clarify its purpose for them?

• It makes the I/O ports of the motherboard available for connection in a variety of computer cases.

• It plugs into the motherboard and expands the number of available slots for adapter cards.

• It provides multiple connections for SATA hard drives to connect to the motherboard.

• It connects the PCIe adapter slots used for video directly to the CPU for faster processing.

Answer explanation

The purpose of an I/O connector plate is to make the I/O ports of the motherboard available for connection in a variety of computer cases. This is the correct choice because it accurately describes the function of an I/O connector plate. The other options, such as expanding the number of available slots for adapter cards or providing connections for SATA hard drives, are not the primary functions of an I/O connector plate.
