Infrastructure Part 1

John is building a new gaming PC. He wants to ensure that the computer has a high-performance graphics component responsible for rendering detailed and realistic visuals in his games. Which component should John consider for this purpose?

• GPU (Graphics Processing Unit)

• Motherboard/system board

• RAM (Random Access Memory)

• CPU (Central Processing Unit)

Answer explanation

The GPU, or Graphics Processing Unit, is a specialized component designed for rendering and processing graphics. It is responsible for handling complex calculations and rendering high-quality images and animations. GPUs are particularly important for gaming, as they significantly impact the visual quality and performance of games. The motherboard, also known as the system board, is the main circuit board that connects and allows communication between various hardware components in a computer system. While it is a crucial component, it does not directly contribute to graphics processing. RAM is a type of volatile memory that provides temporary storage for data that is actively being accessed by the CPU. It plays a crucial role in overall system performance by providing fast and temporary storage for data and instructions. However, it is not directly responsible for graphics processing. The CPU is often referred to as the "brain" of the computer. It performs calculations, executes instructions, and manages data flow within the system. While the CPU contributes to overall system performance, including gaming performance, it is not specifically designed for graphics processing.

Which component(s) of a computer system are involved in graphics processing? (Select TWO).

• Power Supply Unit (PSU)

• Cooling system

• Hard Disk Drive (HDD)

• Random Access Memory (RAM)

• GPU

Answer explanation

The cooling system is responsible for dissipating heat generated by the GPU and other components during intensive graphical tasks, ensuring that the GPU can function efficiently. The GPU (Graphics Processing Unit) is the correct answer. It is designed specifically for processing and rendering graphics, making it a crucial component for graphical tasks. The Hard Disk Drive is the primary storage device in a computer, responsible for storing all data and files persistently, even when the power is turned off. However, it is not directly involved in graphics processing. Graphics processing is handled primarily by the CPU and the GPU, which perform computations and render images to be displayed on the screen. The Power Supply Unit provides the necessary power to all the components of the computer system, including the ones that perform graphics processing. However, the PSU itself doesn't participate in the graphics processing. It only provides the required power for the components to function effectively. RAM is a type of volatile memory used by a computer system to temporarily store data that's being processed by the CPU. While it might store graphical data temporarily during processing, it does not perform the actual graphics processing. Instead, that task is primarily performed by the GPU and, to a lesser extent, the CPU.

Sarah is a computer technician at a large office. She is tasked with setting up and configuring several network printers and scanners for the newly established marketing department. Sarah needs to ensure that the IP addresses for each device are correctly assigned to enable network communication. What type of peripherals typically require manual configuration of IP addresses for network connectivity?

• Plug-and-play

• Driver installation

• Web-based configuration

• IP-based peripherals

Answer explanation

P-based peripherals, such as network printers, IP cameras, or network storage devices, typically require manual configuration of IP addresses for network connectivity. These devices rely on IP (Internet Protocol) addresses to communicate over a network. During setup, you need to assign a specific IP address to the peripheral device, ensuring that it is unique and compatible with the network infrastructure. This manual configuration allows the device to establish communication and connect to the network. Driver installation is the process of installing the necessary software (drivers) to enable proper communication between the peripheral device and the computer's operating system. It does not directly involve IP address configuration. Plug-and-play peripherals are designed to be automatically recognized and configured by the computer without the need for manual IP address configuration. These devices are typically connected to the computer via a USB or Thunderbolt port and rely on the operating system's automatic network configuration capabilities. Web-based configuration refers to the setup and configuration of network devices through a web-based user interface. This may involve accessing the device's settings using a web browser and configuring various parameters, but it is not specifically related to IP address configuration.
